If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
It's always too early to quit.
If you've got a talent, protect it.
Never complain and never explain.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
Always desire to learn something useful.
