Never complain and never explain.
What you do today can improve all your tomorrows.
Leap, and the net will appear.
If you're going through hell, keep going.
It's always too early to quit.
Go for it now. The future is promised to no one.
If you can dream it, you can do it.
Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
If you've got a talent, protect it.
There is no single development, in either technology or management technique, which by itself promises even one order-of-magnitude improvement within a decade in productivity, in reliability, in simplicity.
