New hobby, huh ? Why is everybody suggesting collecting, it's all the same whatever you collect. Maybe you need something that isn't collecting, like learning to play a guitar, using a metal detector (that can turn into collecting though...). How about creating rather than collecting ? Woodwork !!! No good with your hands ? Do modern art, if you're good at "bull" you'll make a fortune too. All you need is a message. Make the "art" first, work out what it means afterwards.
