I can relate completely. I retired & started an LA business. I've only been doing it for a few years, but I find I don't have any time for myself and it really has taken the 'joy' out of it. I haven't made/finished a quilt for myself since January! I love hearing how pleased my customers are w/their quilts and all, but like everything you do day in & day out, it looses it appeal after a while.
I haven't decided to give up my business, but I have been taking the time to enjoy my summer more this year :)
