Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)
It can be interesting to go against the grain, I know. It can also be tough to admit you're not happy when you have a good paying job (or a job at all depending on the current economy), food on the table, and a roof over your head. Heck, you might even like your co-workers. But something still might not feel right to you. It might take you some time, but eventually, you know you need to listen to that little voice that's telling you that you need to make some changes in your life, and it might need to start with your job and career choice. If that means quitting your job, current position, or current workgroup, it's OK for you to make the plans to do so. It's OK for you to make choices that will bring fulfillment to your work and life, and the fact is, you're the only one that can choose do it for yourself.
