I don't get this one: <quote> - Do anything to get a “yes” - Here’s a negotiation I did. I was starting stockpickr.com and meeting with the CEO of thestreet.com. He wanted his company to have a percentage of stockpickr.com and in exchange he would fill up all of our ad inventory. I was excited to do the deal. I said, “Ok, I was thinking you would get 10% of the company.” He laughed and said, “No. 50%”. He didn’t even say “We would like 50%”. He just said, “50%”. I then used all my negotiating skills and came up with a reply. “Okay. Deal.” I’m a salesman. I like people to say yes to me. </quote> How's this a good deal? And also, a good salesman doesn't just want people to say yes, they want people to say yes on his terms, not on their terms...
