I can, therefore I am.
It's always too early to quit.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
Well done is better than well said.
You never know what motivates you.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
This is just what I have thought when I have seen slaves at work - they seem to go through the motions of labor without putting strength into them. They keep their powers in reserve for their own use at night, perhaps.
