Make room for knitting if you want to do it.
I work really hard and a lot. 15 hours at the office are not rare. More happens several times a week, too.
One would think there is no time for knitting. But I am less stressed and more balanced, enjoy life more and feel more accomplished when having something to do while not at work. 1st of january this year I started up again (I originally started 30 years ago and have had busy and quiet times with knitting)... It REALLY makes a difference in my life.
So: If you really want to knit: DO IT. be happy, be proud, don't put stress on yourself and you will see that the structures, knitting puts in your brain will over all help your life and make you complete other tasks in good time.
Enjoy your hobby and make nice stuff!
