Go for it now. The future is promised to no one.

Well done is better than well said.

By failing to prepare, you are preparing to fail.

Either you run the day or the day runs you.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

It's always too early to quit.

Quality is not an act, it is a habit.

Never complain and never explain.
