You have to compete with others in the field. Sometimes the competition gets pretty fierce because you're competing for funds or grants to do your work, the financial work.

That's the way I got along in life. I don't ever remember being particularly jealous of anybody, because I figured if I can't do it myself, I don't deserve to get it.

Young man, I am afraid you are wasting your time. If there were any more planets they would have been found long before this.

You have to have hope. Otherwise, I don't think you could handle it. Of course, you have to have both luck and pluck to make it.
