If you're going through hell, keep going.
You never know what motivates you.
Well done is better than well said.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
Never complain and never explain.
Only the educated are free.
Leap, and the net will appear.
If you think you can do it, you can.
If global cooling will come soon - scientists will lose trust.
