I can, therefore I am.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
If you can dream it, you can do it.
You never know what motivates you.
Quality is not an act, it is a habit.
What you do today can improve all your tomorrows.
Be thine own palace, or the world's thy jail.
Wherever you are - be all there.
Know or listen to those who know.
