That’s 21 friggin’ consecutive times of doing something before you begin to start doing it without having to remind yourself or consciously think of it.
So, if you find yourself motivated to start, but having trouble remaining motivated, see if you can get 21 times of practice under your belt.
I think motivation keeps you going too but it sure is easier when it becomes a habit.
And once it becomes a habit…
So, cut yourself some slack. Things take time.
