Again, if you build an application that solves a problem you are having chances are that it will also help other people. You are the customer, you are the person with the problem and you know exactly what is needed to solve it or make your life less painful using technology. One of the main reasons I see people wanting to become entrepreneurs is to be able to make their own decisions and to be in control, my advice is do what you want, do what your gut tells you!
Fantastic advice! Following this reasoning we started ‘scratching our own itch’ a few weeks ago and are just now kicking our new project into high gear. When you’re building it for yourself there’s no question whether or not your product meets a specific need.
