Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.
Good, better, best. Never let it rest. Till your good is better and your better is best.
Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy.
When something is important enough, you do it even if the odds are not in your favor.
Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence.
A good plan violently executed now is better than a perfect plan executed next week.
There is only one corner of the universe you can be certain of improving, and that's your own self.
