it's not like I mean you have to do something constructive all the time. It's a way to enjoy the life you have and possibly make other ppl happy~ music is one example :P
some like artistic stuff and usually the maker enjoys it when other ppl enjoy his work. Pretty much being creative or doing what you like the most can spread joy~ of course, there's some things that I don't think really work... like how ppl get made when playing a game x_x that seems more stressful than relaxing :f I'd rather laugh than wtv~
