In order to succeed, we must first believe that we can. It is hard for an empty sack to stand upright. Killing the dog does not cure the bite. Learn what motivates you and work hard on it. Living without an aim is like sailing without a compass.
Luck is what happens when preparation meets opportunity.
No one can make you feel inferior without your consent. No one ever dies at the right time. No one reaches a high position without daring. No problem can stand the assault of sustained thinking. Nothing can ever be accomplished without enthusiasm.
