Things do not happen. Things are made to happen.
Never complain and never explain.
If you're going through hell, keep going.
Go for it now. The future is promised to no one.
The secret of getting ahead is getting started.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
To create the power of competence without creating a corresponding direction to guide the use of that power is bad education.
