It's always too early to quit.
Well done is better than well said.
If you've got a talent, protect it.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Go for it now. The future is promised to no one.
Be kind whenever possible. It is always possible.
I can, therefore I am.
There were no PCs when I started programming on computers.
