Routines are powerful automatic habit-makers and slice through the cognitive dissonance of starting/continuing an uncomfortable activity e.g. exercising first thing in the morning instead of being able to convince yourself you're too tired to do it after work from having dreaded it all day.

Try doing it first thing in the morning so it becomes automatic and you experience some benefits from it that will then naturally remind you to keep it up cause it's positively benefiting your life (positive feedback loop).

For me it's the self-awareness/calmness to handle any tough situation and quiet my brain's anxiety/impulsive thinking that keeps me practicing mindfulness/mediation daily, wish you luck!
