I have to disagree. I find the more I share ideas and advice, the more I get in return. The free flow of ideas benefits the giver as well as the receiver. As an added bonus, the more good advice I can give and the more ideas I can share, the more ideas and advice come my way.
You could make an argument that once you've "made it" this exchange becomes asymmetrical. However, I'm grateful for those interactions I've had with people who have "made it" and wouldn't begrudge that to others when/if I have.
I'm reminded of a quote from Howard Aiken:
"Don't worry about people stealing your ideas. If your ideas are any good, you'll have to ram them down people's throats."
