Change is repetition, commitment, perseverance and patience.
Doing it once is not enough, doing every day for months or even years brings about a powerful compound effect.
No perceivable change occurs in the early stages and that is where we most often give in, we wanted the quick fix instant result kind of change, but lasting change takes longer.
But once you build momentum the change is often surprisingly much better than expected and easier then to maintain.
What change will you do at least 99 more times?
