Never be discouraged, because every wrong turn attempt, when left behind you, is another step forward taking you closer to your goals.

Sticking to it is the genius.

The biggest failure of man is that he gives up before he realizes how close he was to success.

Each time you fail, you have eliminated another wrong option.

The three great essentials to achieve anything worthwhile are, first, hard work; second, stick-to-itiveness; third, common sense.

There is no substitute for hard work.
