IMO, getting a habit might need a "click", a resolution. I tried many times to get into exercise, but only got into a regular schedule (daily) recently. I don't even know what happened but there is definitely a click. The number of days is not so important. Something inside just told me to do it. Same with fasting. Somehow I got into 72-hour water fast with zero preparation and "habit" a few months ago and have been doing it once or twice a month. How to get the click is more interesting. I wish I could generate those clicks for things I want to do but not dying to do.
