To know oneself, one should assert oneself.
Never complain and never explain.
Be thine own palace, or the world's thy jail.
Well done is better than well said.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
Problems are not stop signs, they are guidelines.
If you think you can do it, you can.
The dog that trots about finds a bone.
I can, therefore I am.
You don't get old until you replace dreams with regrets.
