How to pick a software project

I found a fine article on picking a software project that could eventually become the basis for a business. The author, Philipp Schumann, suggests picking a project that you would enjoy working on for the rest of your life. Why? Well, it will get you through the ups and downs that you will inevitably go through. You’ll be more willing to go the extra mile. And you’ll be more aligned with the interests of your customers. This is similar to those espousing only working on projects you are passionate about, but takes it a step further by getting past the emotion and makes you think about the bigger picture. The author was probably passionate about creating a sudoku game but didn’t want to be in the games business in the long term.
