Always desire to learn something useful.
If you can dream it, you can do it.
Without hard work, nothing grows but weeds.
Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
Never complain and never explain.
The secret of getting ahead is getting started.
If you've got a talent, protect it.
If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
