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

When you have exhausted all possibilities, remember this - you haven't.

There is no substitute for hard work.

People are not remembered by how few times they fail, but by how often they succeed. Every wrong step is another step forward.

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

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