I like practicing and studying things daily. I am not so into the guilt of skipping a day. My way around it is to make sure my daily practice tasks have a number like "five minutes". If I need to skip a day then I defer the task until tomorrow or some date in the future I know there is more space.

I don't mind arriving to a day and having three "practice drums five minutes" tasks. I can get those done at random times in the day and catch up. That way I know I did the work of drum practice. It allows me to keep on practicing without the daily calendar guilt of habit trackers.

A good system for rehearsal and study. Not a good system for things like taking medication.
