you cannot take constructive criticism, cannot take risks, cannot sell ice to Eskimos, do not have a sense of quirky nerd humor, and most importantly if you do not like eating cereals for breakfast, lunch and dinner for weeks at a time as money is getting tight in your startup budget.
There is a difference between selling someone something that they need but don't realize it yet vs. selling someone something that they don't need. The term "sell ice to eskimos" means you're so good at selling that you can sell someone something they don't need. You don't need that skill in a startup. Sure, good at sales, and sure, good at communicating benefits, but you don't need someone so good at sales that they can sell someone something they don't need.
