Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
Begin to be now what you will be hereafter.
Who seeks shall find.
I can, therefore I am.
Be kind whenever possible. It is always possible.
It's always too early to quit.
An angry man opens his mouth and shuts his eyes.
