People won't have time for you if you are always angry or complaining.

If you believe in science, like I do, you believe that there are certain laws that are always obeyed.

However difficult life may seem, there is always something you can do and succeed at.

Most people don't have time to master the very mathematical details of theoretical physics.

If we do discover a complete theory, it should be in time understandable in broad principle by everyone . . . . Then we shall all, philosophers, scientists, and just ordinary people be able to take part in the discussion of why we and the universe exist.

I have so much that I want to do. I hate wasting time.
