Without hard work, nothing grows but weeds.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
After a storm comes a calm.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
Problems are not stop signs, they are guidelines.
If you're going through hell, keep going.
Only the educated are free.
Be gentle to all and stern with yourself.
The best museums and museum exhibits about science or technology give you the feeling that, hey, this is interesting, but maybe I could do something here, too.
