To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

By failing to prepare, you are preparing to fail.

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.

It's always too early to quit.

Either you run the day or the day runs you.

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

Be gentle to all and stern with yourself.
