How do I honor myself?

I just listened to the latest podcast, Monday Hour One. One of the items talked about as a part of time management, is honoring yourself in doing what you tell yourself you will do. The ability to follow through on what you put in your calendar. Brooke said, “What matters is, do you say you’re going to do something to yourself and then do you do it? And if the answer is no, that’s the problem we have to address.”
This is exactly my problem. So how do I address it? How do I begin the steps to follow through and trust myself?

Thank you!
