I don't believe in over-diversification. I prefer to focus on a few good ideas.

The first lesson reading teaches is how to be alone.

Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.

The real problem is not whether machines think but whether men do.
