I can, therefore I am.
By failing to prepare, you are preparing to fail.
To be a good loser is to learn how to win.
Always desire to learn something useful.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
To know oneself, one should assert oneself.
There are no dreams too large, no innovation unimaginable and no frontiers beyond our reach.
