It's always too early to quit.

Do not weep do not wax indignant. Understand.

Either you run the day or the day runs you.

I can, therefore I am.

The dog that trots about finds a bone.

Always desire to learn something useful.

Know or listen to those who know.

Begin to be now what you will be hereafter.

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