why not not a class, a new hobby AND new friends?! I need to get that exercise one cracked too - don't be hard on yourself, it's difficult finding time to do that much. I'd be pleased with 3 sessions a week! Why not have a little brainstorm and just spend 10 minutes writing down every thing you ever wanted to do - however crazy - and see where that takes you?
