It’s much easier to stick to a habit if you make it a daily habit.
For my whole adult life, I’ve been trying to make a habit out of going to the gym and exercising regularly. I had always assumed that exercising 3 or 4 times a week was enough, so I set rules for myself like: go to the gym at least 3 times a week, or go for a run once every two days. And sure, sometimes I managed to stick to it for a few weeks. But, inevitably, I would be too lazy to exercise on Monday, and Tuesday, and Wednesday, and Thursday. And then I would have needed to go every day for the rest of the week — it seemed too much, it wasn’t the plan to have to exercise every day. I would get discouraged and abandon the whole idea. And then try again a few weeks later.
It wasn’t until I decided to go to the gym every day that I managed to make it a habit and stick to it. Only when a task is non-negotiable, a habit can be built.
