Understand social proof and signaling. Practice dropping positive signals and social proof in all your stories; have a rehearsed story showing vulnerability to have when you need to make yourself appear more personable. Practice mirroring as people like those similar to themselves. If you're an well educated white male, you're already halfway there.
In business, if you are a tough but fair player, and you lose, you will be offered the chance to play again. If you compete in bad faith, you won't.
What do you do when your competitor is willing to break rules that you are not? Tread moral and legal grey areas that you do not? Take advantage of Facebook API's to spam users? How about spamming Craigslist? Submitting thousands of fake car requests to bog down your service and drivers?
Do you avoid all this low hanging fruit? Or do you take advantage of these growth opportunities and hope that you're so successful these shady tactics become afterthoughts?
