In general: Try everything you want to try, keep moving and exploring, and do not be complacent and/or stagnant. Your 20s is meant for exploration while your 30s are meant for stabilisation.
There are some specific exceptions however:
1. Do not disregard your health. You won’t be able to explore as much and then stabilise later on if you’re weak and/or always sick. 2. Try to learn how to invest, at the very least in index funds. Compound interest is much more powerful when started early.
