Always desire to learn something useful.
Problems are not stop signs, they are guidelines.
Who seeks shall find.
You never know what motivates you.
After a storm comes a calm.
Leap, and the net will appear.
If you think you can do it, you can.
Only the educated are free.
The wise does at once what the fool does at last.
Quality is not an act, it is a habit.
God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.
Science already contained all that was necessary, if you just brought it out.
