Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.Thomas Alva Edison
My message, especially to young people is to have courage to think differently, courage to invent, to travel the unexplored path, courage to discover the impossible and to conquer the problems and succeed. These are great qualities that they must work towards. This is my message to the young people. Abdul kalam
Science is a tool, and we invent tools to do things we want. It's a question of how those tools are used by people. Margaret Atwood
You need to feel that the game is important to you. Lose that feeling and you lose your edge. There's no faking that kind of emotion. You can't invent the feeling. It's got to be natural, real. Dan Marino
