Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.

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

Always desire to learn something useful.

If you're going through hell, keep going.

Leap, and the net will appear.

Be gentle to all and stern with yourself.

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

Know or listen to those who know.
