Caring enough to post about the quality of something you're passionate about is immature.
Caring enough to post about what you think is the proper amount to care on a forum to not appear like a baby isn't.
Good to know.
As someone who went through something similar it's actually not that far off. You have a lot of time to work out as a NEET but it's easy to skip on leg day and back exercises.
It's only a matter of time until this doesn't work out anymore and the counter is reset.
In this world nothing can be said to be certain, except death and people pissing themselves.
