Quality is not an act, it is a habit.

If you've got a talent, protect it.

It's always too early to quit.

The most effective way to do it, is to do it.

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

Never complain and never explain.

The secret of getting ahead is getting started.

The wise does at once what the fool does at last.
