It's like art therapy to me. I either have the TV on or listen to music and for whatever reason, it just makes me feel... happy.
Like a room without a roof? Sorry couldn't resist! A hobby is a great idea. Unfortunately, when it comes to painting or doing any kind of craft type project I have zero and I do mean ZERO talent in that area. Perhaps my hobby could be determining the very best tasting scotch...that's better than a room without a roof!
