I am so so so happy that I was able to retire at age 50. Had also worked since age 15 (12 if you count paid babysitting jobs!) and was just so read to get out of the commuting traffic grind, always doing what someone else wanted me to do (rather than what I wanted to do), constantly shifting and changing priorities, and adapting to ever-faster-changing technology (I too was a software developer). I loved MOST of the people I worked with but had been very tired of the general work environment, low morale, more work with fewer people, constant fear of layoffs and seeing so many good people and friends get the ax for over a decade before I was finally able to say "Buh-bye".
I miss some of my co-workers (though most of them are no longer "there" either), but have never missed the politics, meetings, commuting/traffic, and other junk that went with my role. I know I'm fortunate and am very grateful that I am financially able to do this. We never were able to have children and because of that, and investing as much as humanly possible in the early years, DH and I are able to have a comfortable (though not lavish) early retired lifestyle, travel, and do what we want to do, not what someone else decides we should be doing. We are truly blessed.
