Years ago (25+) I quit smoking and took up hand sewing to replace the nervous habit it left behind. Since a child I always found sewing to be relaxing and an avenue for my creative side. Though most of the past 25 years I concentrated on our girls clothing needs (formals/dresses/costumes/wedding gown) I also made my own stuffed animal patterns using old coats & clothing. I then took up Quilting about 6 years ago and found it very addictive too but sewing in any form is so much better for my health.
As for finding time and being focused - when I get into my sewing mood my DH (who is now is retired) knows the signs and works around me. I still work 4 days a week and we do the occasional craft show to help pay for my addiction and a few fun vacations. So in our house, its a win-win situation. He now takes care of things around the house, does most of the cooking/laundry/cleaning, we do craft shows together, camp, hike and travel alot. I bring my hand sewing and sewing machine with me and while DH loves watching TV & Legos, I love to sew. This allows me time to play, think and be with DH - be it in our RV, the motel or on the deck in our backyard.
So to wrap this up a bit, I think focus is based on what your heart wants - want it bad enough you will find the means to make it happen. Look around, see what makes your heart tick a bit faster and see how you can make it happen. Focusing is up to you.
