As long as you feel you want to avoid responsibilities, please do so in a responsible way. Use condoms every time, and don’t get involved with a person who wants children. Be a good support-player at work so your manager doesn’t have to be a bitch (they still might, in which case support your coworkers). And contribute in low-effort ways like donating an occasional pint of blood if you’re eligible, or offering to put someone else’s cart away at the grocery store. Just being a decent person is enough.
