Thought provoking! I had a revelation when I had a meeting with my retirement counselor who showed me I had enough in my account to retire and make the same amount I was taking home from the job, which I was hating. Life is too short, and it's scary to take the leap and give up what is familiar, but it's been 2 years now since I retired at age 58 and I've never regretted it!
Stepping out of the comfort zone can be scary. I am glad you took the leap and reached a point where you have no regrets! Congrats!
