Don't blame people for disappointing you. Blame yourself for expecting too much.
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.
Don't blame people for disappointing you. Blame yourself for expecting too much.
Life is so constructed, that the event does not, cannot, will not, match the expectation
Sometimes it's not what you expect, and it's not what you want, but it's exactly what you need.
