The fifth time you arrive exactly when you said, people quit keeping a backup plan for you.

Trust is not granted by a promise, it is granted by a pattern. People hold a quiet contingency for everyone until the evidence says they can stop, and that evidence is boring and cumulative rather than dramatic. Once the backup plan disappears, you start getting the things that only go to people who do not need supervising.

Think about where someone is still hedging on you. Show up on time to that specific thing several times in a row without mentioning it. The fifth one is what changes the arithmetic, not the first.
