It is inspired by Jerry Seinfeld’s Productivity Secret:
”Get a big wall calendar that has a whole year on one page and hang it on a prominent wall. The next step is to get a big magic marker.
For each day that you do your task, put a big mark 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.”
