Yes, attitude, but you also have to ask what you think makes a "successful entrepreneur". Sales; knowledge rarely helps here, attitude, being able to read people, knowing people, knowing how to make people want your solution to their problem. Being able to handle rejection over and over (those first 10 legitimate paying customers can be tough) Software development; knowledge is important for a proprietary technology (a search/data algorithm) but most web technology projects aren't top secret. Knowledge might help much more at a defense think tank. But for non proprietary stuff, attitude is important because you want to connect with the business use cases, you'll likely have to do "stupid" stuff for repeating obvious solutions. Executive; much more in line with sales; attitude is important; many other people have knowledge here and your job is to choose the one that you sell to your customers, employees, and executives. --- Otherwise, "ignorance is bliss", attitude will help you much more than knowledge in life.
