Understand your users

Understand your users. That’s the key. The essential task in a startup is to create wealth; the dimension of wealth you have most control over is how much you improve users’ lives; and the hardest part of that is knowing what to make for them. Once you know what to make, it’s mere effort to make it, and most decent hackers are capable of that.

Go to your target market

Ultimately, the best test of any product is to go to your target market and pretend like it’s a real business. You’ll find out soon enough if it is or not. You have to take some risks. You can sit and analyze these different markets forever and ever and ever, and you’d get all these wonderful answers, and they still may be wrong. The problem with the businessman type is they spend a lot of time with all their great wisdom and all their spreadsheets and all their Harvard Business Review people, and they’d either become convinced that there’s no market at all or that they have the market nailed.
