What should I do?

do you know those days when you do nothing and then you feel like shit because you did nothing? although work sucks, it's a lot more fulfilling then just sitting on your ass. Lately all i have been doing is smoking which is fun but i want to find somthing to do that makes me feel good after the fact. so basically im looking for a hobby to get into. gaming is pissing me off and i edit but it is at a stand still for the moment. what are fun things to do?
