Desire is transformed into drive when a dream creates a passion for action
Worry comes from the belief you are powerless.
All our experiences have led us to believe certain things about ourselves. Whether these beliefs are true or not really doesn't matter because if we accept them as true, then they are true for us.
Pronounce your limitations vigorously enough and they're yours.
If you want to know what your true beliefs are- take a look at your actions.
A person who knows who they are is not threatened by the beliefs of others.
