You never know what motivates you.
Problems are not stop signs, they are guidelines.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
Leap, and the net will appear.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
In science there is only physics all the rest is stamp collecting.
