This is so true, I always have at least 3 things keeping me busy between guns, guitars, projects cars, and also my work... As long as your busy depression isn't possible, when you sit idle everything minor you ever did wrong starts to hurt you. Being busy with things you hate will depress you however, college was a bad time for me because I just hated listening to all the leftists and not having a way to tell them to fuck off...I honestly shouldn't have went but boomer parents practically forced me. In the end I got a good degree that wasnt gender studies so not all was wasted but I don't think it was worth it still.
