Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
Leap, and the net will appear.
To know oneself, one should assert oneself.
It's always too early to quit.
Things do not happen. Things are made to happen.
What you do today can improve all your tomorrows.
Well done is better than well said.
Only the educated are free.
After a storm comes a calm.
Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.
