Arts. If you can tolerate the Joollywood, ofc. And if you can produce anything.
Les belles lettres require only a calculator with word processor on it. Music can be produced with pirated software and/or quite affordable instruments. One instrument is enough for months, if not years.
Painting is trickier, good paints can bite the wallet.
Aaand thats it. Other arts require more people and/or way more money an individual can scrub.
