Quality is not an act, it is a habit.
What you do today can improve all your tomorrows.
Problems are not stop signs, they are guidelines.
The most effective way to do it, is to do it.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
After a storm comes a calm.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
As for everything else, so for a mathematical theory: beauty can be perceived but not explained.
