Martin Luther King is a great model for anyone who wants to change careers. King was a minister and could have stayed in his church. He would have done good work and helped many people. However, he had a higher calling. The minister became a champion for civil rights, and he changed history.
King's own words are invaluable for anyone looking to change careers or make any major change in life: "Faith is taking the first step even when you don't see the whole staircase."
I changed careers when I turned 40. That was 14 years ago. There were plenty of starts and stops, interviews that felt like a waste of time. Finally I found a place to start my new career. Several of my clients have had similar experiences. As Dr. King said, "faith" is the key. If we believe in ourselves, we'll see the "whole staircase" and find our new path.
