Always desire to learn something useful.

Quality is not an act, it is a habit.

Know or listen to those who know.

Do not weep do not wax indignant. Understand.

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

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.

To know oneself, one should assert oneself.

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