Things do not happen. Things are made to happen.

Always desire to learn something useful.

The dog that trots about finds a bone.

If you're going through hell, keep going.

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

By failing to prepare, you are preparing to fail.

Do not weep do not wax indignant. Understand.

It's always too early to quit.

Know or listen to those who know.
