Ancient coins (2000-1700 years old) are surprisingly common and can be had very cheaply unless you want a specifically rare or perfect one.

I went through most of my life believing that anything older than say 200 years was automatically a museum piece or equivalent. But most museums of ancient history who display ancient coins have multitudes of the displayed coins sitting in storage. The Romans alone minted BILLIONS of coins over the span of the Republic and the Empire (that’s over 1000 years of history!) and if even 1% of them survive today, that’s still many, many dozens of millions.

Observing groups is a very useful skill, in minutes you can tell who’s where in the hierarchy, what the cliques are, how well they coordinate, how information flows, and where influence springs from.

This let’s you not only insert yourself at the right moment, peg, and place for maximum efficacy, but also informs you of barriers, challenges to overcome, and next steps for the group to act better together.

Its easier to make gamers into friends than it is to make friends into gamers

There’s two types of costume contests, cosplay contests that break things down by experience, and random Halloween contests that are basically reenactments of popularity contests in high school.

The former you’re gonna enter as a journeyman unless you built something so outrageous they gotta up the difficulty level. Make sure you have a TON of documentation and pics and explanations on how you did things. The judges are gonna wanna know how hard you worked on things and the amount of detail you put into it. If you spent 8 hours on the gold colored filigree on your bracers you damn well better mention it Typically unless you’re doing best performance, you get three poses and you’re off the stage. By the time you hit the stage the judges typically made their decisions so play to the crowd and do what looks good on film. If you are going for best performance, don’t feel pressured to use your full five minutes, or however long they give. Waaay to many people overstay their welcome, you wanna leave the people wanting more, not less. Hit your points, your high note, and if you’re still only halfway through your time, whatever. You’re not disqualified if you don’t use your time completely, and people will greatly appreciate someone moving the schedule faster than usual.

For the latter Halloween costume contests, effort means NOTHING. You could’ve thrown the damn thing together in five minutes and win, and if you spend 16 hours on it it will not improve your chances. The venue is looking for costumes that look great on the social media, is a character they love, makes them laugh, blows their mind, causes the venue to cheer, and (this is the most important bit) appears in front of whoever the hell is judging the competition. It’s 1 to 3 people who pick on the previously mentioned criteria. Each judge is gonna be a little different. Some judges listen to the crowd, some judges love horror films so every slasher villain goes on stage, some judges do NOT know what the hell a star wars is. The one thing that all judges have in common though, is that they exist in a 3 dimensional space and only have eyes in front of their head. If you’re a wall flower that doesn’t interact with people, you will not win the contest unless the judge is also sharing your wall. Build a dance circle, tip the bartender to figure out who’s judging tonight (they may or may not know) but if you wanna win, physics dictates that you appear in front of a judge as they wander the venue. That is more important than your costume.

Get a heart rate sensor (wrist or chest) and train by heart rate. Most of your cardio should be heart rate zone 2 on the 5 zone scale. This builds your aerobic capacity with minimal damage and can be done almost indefinitely. Harder efforts do more damage and add recovery time so should be limited to about two a week.

If you’re going slow you’re doing it right, it will suck less, and you’re more likely to continue. Your slow speed will get faster over time.

If you ever start playing Warhammer 40k the miniature game and plan on building your own miniatures use magnets on the weapons. A lot of models come with 2 or 3 different weapons that are good for different situations IE better anti tank, fly, infantry ect. Instead of buying the same model 3 times building and painting it you can buy one, attach small magnets to the weapons and the part of the body they attach to, then you can switch them out on the fly. I didn’t do that when I started and it gave me a lot of issues with some of the armies I played against.

One of the biggest things that most amateur filmmakers or video makers make is not getting sufficient tone.

Before shooting, record a fairly long stretch of just the ambient sound in the area where you’re filming so that when you are editing, it can be laid under the audio tracks and help to smooth out the jumps in audio from different clips.

Protection goggles when removing supports from your resin 3D prints. ALWAYS

For Rpg : let the player take the initiative and bring their plot to the table. If they preptge game for you, it’s les work as aGM (also no doodle scheduling, use fix dates)

For paragliding : if there is nobody on a flight site do not take off. Most likely you misunderstood something, and the site isn’t flyable. Sure if you re very experienced, do hike and fly or do fly on a week day on a small site, it may not apply, but you’re able to analyse by yourself

In Magic the Gathering it’s usually correct to wait to play instant spells until your opponent’s turn, either on their upkeep or end step in most cases. Waiting as long as you can gives you more information to make the best play.

I learned the hard way when jogging and meeting some friends at the bar that even if it’s plus 20 you should bring a sweater with you, because once you’re done jogging and it gets dark you will be cold from the sweat. I did this one time and everyone else in the bar was just fine with their T shirts and I was SHIVERING with my wife beater on. Kind of embarrassing.

Hiking/backpacking (not exactly niche?)

1. Don’t buy a ton of stuff for day hikes. You need less than you think. If you carry enough for an overnight there is a good chance you’ll be so slowed down that you’ll end up staying overnight.
2. Carry the ten essentials. GPS’ run out of battery and you can end up in areas without satellite reception. Always have a compass and paper map and visualize your route before going if you are backpacking in deep. Be aware where roads and bailouts are relative to your route.
3. Occasionally look behind you to get an idea of what the route back will look like if you’ll be returning the same way.
4. If it doesn’t look like a trail, stop, you need to backtrack to the last sure spot. Don’t plow ahead blindly thinking it will resolve itself.
5. Winter hiking means less daylight and more stuff (slower). Plan accordingly.
6. “Mountains generate their own weather”. Bring some light raingear and insulation even if it is warm at the trailhead. I’ve started in 80+ temps and gotten snow near summits.
7. Carry hiking poles. They are invaluable for things like stream crossings. They saved me from breaking a leg stepping down boulders once.
8. If the trail is blazed and you can’t see them look up and behind you for them, sometimes they are painted high up for snowpack.
9. Carry traction (ice creepers) if going up into the mountains in spring/fall. Early/late snow and ice is common. In winter bring crampons.
10. Always check the weather, especially for mountain hikes. Be ready to turn back or change your plans if the weather looks sketchy. Don’t get “summit fever” just because you made a special trip.
11. If you are shopping for gear spend the most on boots. They will be the major deciding factor in how comfortable your hiking is. Make sure to break them in before a trip. I’ve been on a multiday mountain trip where a guy had brand new boots and his feet were bleeding by day 3.
12. If winter hiking and there is a snow pack wear gaiters (or built in ones). Snow in boots = cold/wet feet = frostbite. I’ve seen too many people have to turn around because their boots were getting packed with snow and they were suffering.

Buying a cheap 2nd hand E-bike (right now) means the same as buying any other broken bike: You need to know how to switch a chain and adjust brakes. The electronics themselves however are surprisingly resilient.

As someone who enjoys growing and studying about many many different kinds of carnivorous plants, don’t worry too much about feeding them, instead make sure you get them enough lighting and good water supply through good quality substrate (not something that’s been decomposing for 3+ years and turning into mulch) with adequate aeration. The need for metabolic energy always comes first before nutrition (which is what these plants get from eating meat), same concept to how not having access to oxygen to breath is a lot more dangerous to a human or animal than being malnourished.

Happy growing! :D

Closest I got to a hobby is reading a shit ton of books. Highly recommend listening to an audiobook while you read a physical copy, cannot stress enough how much this helps me focus.
