I totally agree on consistency being the hardest obstacle to overcome when it comes to achieving what we define as success. In fact, our education only prepares us to accomplish short term goals such as taking tests and exams that we pretty much don't think about once we complete formal schooling.
I feel we need to have a deeper more innate desire to do the things we want if we aim to achieve consistency. It goes beyond fame and fortune. The real driver is answering why, what, when, where, and how to turn that goal into a reality.
