Yeah you gotta be careful with that, especially in today's "lockdown culture". If you don't keep it up your muscles will atrophy and/or turn to fat before you know it.
Seems we have a lot of the same hobbies though. One of my favorite things to do is to go somewhere and get above/away from the pollution and just look at the stars that you normally can't see with all the smog. It's so pretty to see how they fill the sky and then i think "This is the sky our ancestors knew."
Yeah i used to burn myself out for fun. Then one day i realized that it's actually a really really bad thing to do, so i kinda just...stopped. It's not as easy as it sounds though, and meditating that **** out of your system is a lot harder to do if you're not used to it. It's a skill that comes with practice though, and i practiced for a very long time until i was actually pretty good at it. Needless to say, i've been practicing a lot more lately, haha. Even so, it's still annoying more than anything when you want to finish something and you can't manage to do so, even if the outcome would be incredibly sweet, poignant, and meaningful.
