Checkboxes (one per day, per task), especially effective if public and you don't want others to see you missed a day

Task lists, cross off and rewrite as needed

Counters (a flip day counter where you press a button and it flips over a new number), to keep streaks (nofap)

Make your darn bed.

Learn how to keep tidy and have a exercise routine, Drink a cup of warm water every single day. Makes you more friendly and patient.

Any time I get into a discipline rut I fall back to the old standard of lists. Today, tomorrow, this week lists. Or prioritize by importance: High, medium, low.

The idea is to have your list, then process to completion. Gives you a feeling of accomplishment, even if you are only doing online stuff or emails etc and that positive reinforcement helps you keep it going.

Also, need a good calendar app like Rainlender and anytime something you need to do or remember comes up, put it on the calendar.
