Just keep trying things and find what you enjoy. Could be hiking, bicycling, running, lifting weights, yoga, boxing, rock climbing, etc... there's all sorts of stuff and all of them come second to diet
two days a week I go to a commercial gym now. Most people there are more about looking good. There's this one tall guy that was acting like a jerk to me for no reason. He just kinda acts that way and only talks to the people who look like they've been bodybuilding for years... I don't really let it get to me. I'm not training to for appearance and no matter how fit that guy gets he'll still have a shitty personality
Most early SCUBA injuries come from either the student or the instructor ignoring the concerns of the other, and later on it's about the diver getting cocky and dismissive of safety precautions.
(My dad was a master instructor trainer, meaning he taught people how to teach SCUBA. He also taught night diving and cave diving, gave week-long tours on remote islands, and had a reputation for teaching the unteachable--like the severely hydrophobic, or a guy paralysed all down one side of his body.)
One use I'm thinking of is having all the PDFs for my collected 300+ RPG systems on a USB stick, and using TiddlyWiki for sorting and notations.
Once I know what game I want, I can retrieve it easily enough. The challenge is in, for example, saying "I want a one-shot premade horror adventure, but I don't care what system." The way I'm set up right now, I'd have to go to every system folder and check if it's got a pre-made horror adventure.
So if I'm going to have to handle every file individually anyway... I might as well go for something which rewards me for that individualised attention, like TiddlyWiki where I can also make custom notes on each file as the whim strikes me.
(And it'd let me retain the organisational structure across operating systems.)
one thing i dont like about the main note apps is the syncing of creative ideas to faceless cloud services.... it's likely all this data will be skimmed to further all this AI or neural network software
