There was a guy I was reading about in the 1700’s whose wife was 10 minutes late at the dinner table every [night] so he took those 10 minutes to work on a novel and he ended up writing 3 very successful novels that way by squeezing in those 10 minutes. I think that’s the trick is giving yourself that time and scheduling it in.
from this interview with Mark Frauenfelder.
I love that idea of even just in 10 (or 15 even!) minutes a day, you eventually DO have something to show for your time.
