The only source of knowledge is experience.

Research is creating new knowledge.

Perseverance is not a long race; it is many short races one after the other.

Be brave. Take risks. Nothing can substitute experience.

Out of difficulties grow miracles.

Quality is everyone's responsibility. 

Set your goals high, and don't stop till you get there.

There is nothing permanent except change.

When all else is lost, the future still remains.

Where there is no vision, there is no hope.
