Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Leap, and the net will appear.
Only the educated are free.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
The most effective way to do it, is to do it.
Be gentle to all and stern with yourself.
I would think twice about designing stuff for which there was no need and which didn't endure.
