Quality is not an act, it is a habit.
Always desire to learn something useful.
If you can dream it, you can do it.
The most effective way to do it, is to do it.
The dog that trots about finds a bone.
Expect problems and eat them for breakfast.
Leap, and the net will appear.
Either you run the day or the day runs you.
