No is the smallest word and yet the hardest. For me, it is hard to sit in front of the laptop after a long, tiring work day. But I want to write, so I gave up 80% of the TV I was mindlessly zoning out in front of.
The other thing that helps me are teeny tiny goals, as suggested by Shaunta Grimes. I experimented with writing daily for NaNoWriMo and failed. Twice. Then I took on Shaunta’s idea, and set myself a tiny goal of 150 words a day. That’s so small, yet doable. When I am able, I write more. And a minimum of 1050 words in a week is far better than none.
Like you say, creating is a series of tiny steps. But if we put them together in a single direction, we can go far.
