I realize that what I will say is rooted in driving, not riding; but, the principle is the same.
When my daughter had learned to drive she was a pretty cautious driver. However, she was getting annoyed by the lapses she saw around herself. This was understandable, she had learned what to do and she saw others not doing it.
The problem was that the annoyances were upsetting her and the upset was becoming a distraction to her driving. I told her something that I often repeat to myself. It turned out that she later used it as a frequent line when she was working as a police officer. "You an only drive your car, you can't drive their car, drive your own car and drive it well." The same applies to bikes.
