The most important person to prove it to is the one in the mirror who’s heard all your excuses.

You are the only witness to every promise you made and did not keep, which is why your own opinion of yourself is so hard to shift with outside praise. Other people see results. You see the gap between what you said on Sunday night and what happened on Tuesday.

Pick one small commitment and keep it for two weeks, something so ordinary that failing would be faintly ridiculous. Trust in yourself gets rebuilt through kept promises rather than through declarations. Start with one you are confident you can keep.
