“Personally, I know going into any new company that there is a 90% chance we have the business model wrong on day 1. I also know that I have a historically poor track record for understanding what will and won’t attract customers or defeat competition (I didn’t get Twitter when Obvious Corp first launched it without an “e” in the name, I thought eBay would be out of business in six months after Amazon launched auctions, and I was certain Netscape would crush Microsoft in the browser wars because Netscape was more nimble).”
