I say do what you like! Keep learning new things, it keeps your mind active and may help symptoms of old age away.
I wish I had more time to do the things I love, I love scrapbooking and I am a new quilter. I also would like to sew for my grandaughters. I love to cook and we remodel houses, some we flip and some we rent. I still work full time, 4 - 10 hour days so I can keep my grandbaby one day a week and I keep the other one one night on the weekend. Whew, seeing this in black and white makes me tired and I see why I neve have time for my hobbies.
