Manual for Myself or Integrity With Myself?

There seems to be a manual I have for myself. When I fulfill the expectations, I feel confident and accepting of myself. When I don’t I put myself under pressure, and have been learning to manage my mind and feel more accepting thoughts and feelings.

What is different or what should I consider about keeping ‘integrity’ with myself (doing what I say I will do)?

For example, today I broke my Monday Hour One work routine for the day, and broke the commitments I had with myself in the schedule. As I reflect on the standard I set and expectation I had for myself, I want to build integrity and trust myself. But I wonder how this is not also putting myself under pressure and not accepting myself. It seems conflicting, like a fine line and I don’t see the distinction clearly.

How do I distinguish integrity from not accepting myself with a manual?
