Never complain and never explain.
Either you run the day or the day runs you.
The secret of getting ahead is getting started.
Go for it now. The future is promised to no one.
Who seeks shall find.
Do not weep do not wax indignant. Understand.
I can, therefore I am.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
The most effective way to do it, is to do it.
Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
