Expectations are what is expected of a person or thing, and somethings these may be unrealistic. If you have high expectations then you may find it is very difficult to meet the goals that you have set, and you could end up disappointed. If your expectations are too low for yourself then you may never achieve your full potential.
If you're going to go to the next level, your values are going to have to change!
You must expect great things of yourself before you can do them.
