It also helps you brainhack yourself into learning more thing, and being more open to other people's perspectives. Not all of these will be valuable, but some of them will be, immensely so. If you have success based solely on your own perspective, it's easy to think you have it all figured out already and overlook where there's room for improvement and outside input.

A critical component to learning is letting other people see your thoughts and ideas and get them to criticise them. This part is much much easier to do if you aren't humble about it, you only need a tiny bit of humility to read and understand others ideas, anything above that will just hurt your ability to learn.

The most common thing people do is the opposite of the above. They are humble with their own ideas and are scared to show them to people, while they are confident in shooting down others ideas so they don't learn that well from listening. Even people who see themselves as humble are usually following this worst of the worst strategy.

Not sure about it. To set higher standards for yourself than for others is already a form of arrogance but you will ultimately improve faster.
