Never complain and never explain.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
Only the educated are free.
The most effective way to do it, is to do it.
You never know what motivates you.
Be thine own palace, or the world's thy jail.
Always desire to learn something useful.
The secret of getting ahead is getting started.
What you do today can improve all your tomorrows.
The reason people find it so hard to be happy is that they always see the past better than it was, the present worse than it is, and the future less resolved than it will be.
