Cooking, baking, wood carving, writing a novel, lockpicking, maybe DIY (learn some plumbing, electician, tiling skills), glass blowing, drawing/painting, instrument...
Get basic idea of entry level requirements, spend 20-50 hours practising move on if you don't like it by then.
Pick something out of any profession and go at it. I am kind a thinking about shoe making or sawing/clothes making.
