Fear of unknown, consequent failure and complacency are some of the major reasons for resisting change. There are some people out there who have no fear of the unknown, and who can simply decide logically what they want to do and do it, but for the rest of us, we have to make the unfamiliar feel familiar.
Fear of failure is a genuinely scary thing for many people, and often the reason that individuals do not attempt the things they would like to accomplish. But the only true failure is failure to make the attempt. If you don't try, you gain nothing, and life is too short a thing to waste.
Find happiness in your job.To be effective, you have to be happy doing what you are doing. If your job is to stressful, boss is giving you a hard time or you are not happy, quit. Yes, quit that job and find one you really can enjoy. This will boost your creativity, productivity and joy.

My father could have been a great comedian but he didn't believe that was possible for him. So he made a conservative choice. Instead, he got a safe job as an accountant and when I was 12 years old, he was let go from that safe job and our family had to do whatever we could to survive.
I learned many great lessons from my father. Not the least of which was that you can fail at what you don't want, so you might as well take a chance on doing what you love.
