Restlessness is discontent and discontent is the first necessity of progress. Show me a thoroughly satisfied man and I will show you a failure.

No, I haven't failed thousands of times. On the contrary, I have successfully eliminated thousands of ideas that do not work!

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

The successful person makes a habit of doing what the failing person doesn't like to do.

I would like to ask you, what would you like to be remembered for? You should write it down. It could be an important contribution, whether it is an invention, an innovation or a change that you bring about in society that the nation will remember you for.

Of course I would have preferred success; but failing in that, I have no regrets for having rejected all advice to the contrary, and resolutely made the struggle.
