Never complain and never explain.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

You never know what motivates you.

The dog that trots about finds a bone.

Go for it now. The future is promised to no one.

Always desire to learn something useful.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.
