To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
Leap, and the net will appear.
Always desire to learn something useful.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
If you've got a talent, protect it.
If you're going through hell, keep going.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
In order to succeed, your desire for success should be greater than your fear of failure.
Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success.
Always be yourself, express yourself, have faith in yourself, do not go out and look for a successful personality and duplicate it.
A successful man is one who can lay a firm foundation with the bricks others have thrown at him.
Success is not final, failure is not fatal: it is the courage to continue that counts.
Think twice before you speak, because your words and influence will plant the seed of either success or failure in the mind of another.
Success consists of going from failure to failure without loss of enthusiasm.
Try not to become a man of success, but rather try to become a man of value.
I don't know the key to success, but the key to failure is trying to please everybody.
Always bear in mind that your own resolution to succeed is more important than any other.
