Never complain and never explain.

Well done is better than well said.

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

If you're going through hell, keep going.

Know or listen to those who know.

Do not weep do not wax indignant. Understand.

Begin to be now what you will be hereafter.

By failing to prepare, you are preparing to fail.

The secret of getting ahead is getting started.
