Hmm, pick it up when you want, but then enjoy your playing for what it is then, at that moment. Then one foot in front of the other. No expectations, just enjoying it for what it is now, a pleasant hobby. You have that nagging feeling that you might regret a sale for a reason. You will come back to a greater interest in it when you are ready. It is a hobby after all, for you and for a lot of us. I always have to remind myself of that. Otherwise I can drive the fun out of it.
