Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
You never know what motivates you.
Do not weep do not wax indignant. Understand.
If you think you can do it, you can.
It's always too early to quit.
The most effective way to do it, is to do it.
Well done is better than well said.
Either you run the day or the day runs you.
There were no PCs when I started programming on computers.
