Excellence can be obtained if you:
care more than others think is wise; risk more than others think is safe;
dream more than others think is practical; expect more than others think is possible.
Carry out a random act of kindness, with no expectation of reward, safe in the knowledge that one day someone might do the same for you. -Princess Diana
If you accept the expectations of others, especially negative ones, then you never will change the outcome. -Michael Jordan
I have very high expectations of myself. I'm a very competitive person but competitive with myself. I want to be the best that I can be and if that means that I'm eventually better than everyone else then so be it. -Wentworth Miller
Never expect. Never assume. Never ask. Never demand. Just let it be. If it's meant to be, it will happen.
