Cathy Scott writes in Forbes on how to leave an unsatisfying job and pursue your dream career:
How-to guides are regularly published about the process of pursuing new careers. I, however, don’t believe a guide can show you exactly how to do that. You have to first believe in yourself, and then take a risk. (my emphasis) Otherwise, you will stay in a dead-end job afraid to step away from your comfort zone.
I see a lot of people who keep looking for those "how to" guides. They want steps, a road map, an expert who will show them exactly how to do it. But what they really want is certainty and safety of the kind that they think they have with their unsatisfying job. The devil you know is better than the devil you don't.
Having struck out on my own to create my own dream career, I know that what Cathy says is correct. It isn't about "how to" guides. It's about being willing to choose what you love, being willing to choose happiness over safety. It starts with believing that you can do it and then taking the risk. It's about making the leap.
Sure, eventually you will want and need practical information about how to move forward. Maybe you will need new education or training. Maybe you want to start your own business and will need help in doing that.
But the biggest step you will take in pursuing your dream is to allow yourself to have it. The second step is finding the courage to pursue it. Don't look for the "how-to" guides that will make you do this. The only place you can look is within yourself.
