I retired a few years ago, bought a new sewing machine, and began teaching myself how to quilt. For a while I was able to quilt 3 or 4 days a week almost all day long ... and loved it. Unfortunately, my mother had some serious falls and also developed dementia, so she has required a lot of my time. Since I've had no time to make quilts, I've been doing some hand embroidery in the evenings. So, "yes" you can sew as much as you want ... as long as life doesn't get in the way.
I try to keep my sewing area organized but I'm usually looking for something. Don't buy magazines. The only reason I have a fabric stash now is because Hancock's here closed and I had $100 in gift certificates to use up. I typically would only have enough fabric on hand to do 2 or 3 quilts. Nowhere nearby to take classes ... not that I'm much on doing that anyway with all the info available online.
Just go for it ... see what works for you ... enjoy and have fun!
