The classic advice is pg's essay "How to Make Wealth" (http://www.paulgraham.com/wealth.html):

"At Viaweb one of our rules of thumb was run upstairs. Suppose you are a little, nimble guy being chased by a big, fat, bully. You open a door and find yourself in a staircase. Do you go up or down? I say up. The bully can probably run downstairs as fast as you can. Going upstairs his bulk will be more of a disadvantage. Running upstairs is hard for you but even harder for him.

What this meant in practice was that we deliberately sought hard problems. If there were two features we could add to our software, both equally valuable in proportion to their difficulty, we'd always take the harder one."

In addition, I would say: (1) provide extremely good customer relations (any post submitted to your site blog or email sent is answered in half an hour max) and (2) use your personal network, Yahoo is not a person, so it doesn't have any friends, you do. Use them and their friends.
