I wish you the best of success in your endeavors. You have achieved more to date than most people achieve in a lifetime. I am sure you are greatly respected by your friends and the critics. No problem in a change of pace. I am sure that there are people who will carry forward, and you will be permanently or temporarily missed for sure. You will regain your love for looking out the spaceship window. The passion ebbs and flows like the tide in some people. We all await your reports of how things are going in the near and longer term.
Good luck.
