I think some of you are missing the point. Pushing that boulder does not look easy and simple; you have to really push yourself to make your dreams (in this case, expectations) into reality.

It is not easy to realize your expectations and that is why you need to work hard for it.

It is not about lowering your expectations at all.

Once you are able to realize your dreams (expectations), then you will feel happy. (i.e, passing a certification exam, building your social and professional network, meeting body fat percentage goals, or whatever your dreams may be).
