To know oneself, one should assert oneself.

Always desire to learn something useful.

Without hard work, nothing grows but weeds.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

Quality is not an act, it is a habit.

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

If you're going through hell, keep going.

Expect problems and eat them for breakfast.
