It's always too early to quit.
Without hard work, nothing grows but weeds.
Well done is better than well said.
I can, therefore I am.
By failing to prepare, you are preparing to fail.
If you've got a talent, protect it.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
Begin to be now what you will be hereafter.
The most effective way to do it, is to do it.
To err is human, but to really foul things up you need a computer.
