“Success is peace of mind, which is a direct result of knowing you did your best to become the best that you are capable of becoming.”
With this definition, it doesn’t matter what industry you work in, or how much money you make. It doesn’t matter where you grew up or who you know. This says that success is all a matter of our own efforts, and how we see how we are doing. And it leaves room to say that we are “becoming” – which is great, because we are all changing, and growing, and succeeding every day, every minute!
