Here's a really interesting article: "Is Giving the Secret to Getting Ahead"? from the New York Times. It's about a Wharton Professor that sounds just too good to be true:
"For Grant, helping is not the enemy of productivity, a time-sapping diversion from the actual work at hand; it is the mother lode, the motivator that spurs increased productivity and creativity. In some sense, he has built a career in professional motivation by trying to unpack the puzzle of his own success. He has always helped; he has always been productive. How, he has wondered for most of his professional life, does the interplay of those two factors work for everyone else? (from "Is Giving the Secret to Getting Ahead"?)
Now I happen to believe in "what goes around comes around." And I try hard to help people without wondering whether I will be helped in return. I can't say I was born that way, but it's just been my experience over the years that I seem to always get more in return than I put out.
Ok. But if you read this article, no matter how helpful you think you are, you're not going to feel helpful enough. I guess there's always room for improvement!
