Jerry Seinfeld used this exact technique to become a great comic. As told by software developer Brad Isaac when he asked Jerry for career advice[0]:
He told me to get a big wall calendar that has a whole year on one page and hang it on a prominent wall. The next step was to get a big red magic marker.
He said for each day that I do my task of writing, I get to put a big red X over that day. "After a few days you'll have a chain. Just keep at it and the chain will grow longer every day. You'll like seeing that chain, especially when you get a few weeks under your belt. Your only job next is to not break the chain."
"Don't break the chain," he said again for emphasis.
