It's always too early to quit.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
Never complain and never explain.
Leap, and the net will appear.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
If you think you can do it, you can.
If you've got a talent, protect it.
If you can dream it, you can do it.
Science is a differential equation. Religion is a boundary condition.
