[mna_]

I have 2 hobbies: maths and chess. For maths: I borrow books from the library or pirate them from anna's archive and do problems from the books on printer paper. Very cheap hobby overall. For chess: I bought cheap plastic pieces and a board from amazon (cost me £25/$30), I pirate chess books from anna's archive and I play on lichess (it's free).

Also without sounding like an elitist: not all hobbies are equal. I have so much more respect for someone who sits in their room and studies something difficult like analytic number theory, or someone like you who powerlifts over some "Disneyadult" whose life revolves around buying Made-in-China Disney branded products (i.e. their hobby is just clicking "buy" on some site).
