Never complain and never explain.
The dog that trots about finds a bone.
After a storm comes a calm.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
Problems are not stop signs, they are guidelines.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
Leap, and the net will appear.
The wise does at once what the fool does at last.
Most of man's problems upon this planet, in the long history of the race, have been met and solved either partially or as a whole by experiment based on common sense and carried out with courage.
