1) Your ego/flesh WILL rise up, multiple times and in many ways, and try to maintain the status quo, even if the status quo is or has been extremely uncomfortable.
2) People, some of those closest to you, and many observers in the cheap seats, WILL criticize and provide multiple reasons why this shift or decision you've made is doomed to fail.
3) The Universe WILL ask you multiple times, and in many ways if you are serious. Not so IT knows. So YOU know.
So why in the world, if there is so much that seems to be against you when you embark on and follow through with your radical shift or decision, would you do it?
No grand endeavor would be grand WITHOUT these things.
YOU have a grand endeavor still in you that you have not yet realized. What are you waiting for?
Trust your gut.
Use your head.
Follow your heart.
