Its so true that people become what you expect them to be.
Its a vicious cycle.
If your expectations are low, its transmitted subconsciously and others feel all they need to do is to live up to this lower expectation. And so they don't live up to it, and you lower your expectations even more so that you yourself will not get disappointed. Etc etc etc.
But how do I increase my expectations without being unreasonable and without being too demanding?
That's a hard one.. still learning. =(
