Have high expectations for yourself and low expectations for everyone else.
If you have low expectations for other people, then their average performance will delight you. Suppose you eat at the finest restaurant in the world. If your expectations are too high, then you will be disappointed, even though you just ate the finest food in the world.
If you have high expectations for yourself, then you will accomplish everything that you are capable of accomplishing. Those who accomplish much are rewarded, and that is how you get the wherewithal to eat at the finest restaurants.
