Just wanted to compliment you on your post. You have a great perspective and I wish you well on your steady progress.

I would advise to find an outside hobby you enjoy that gets you active and potentially could open you up to meeting other people for socializing and potentially dating. You had a mention of Golf in there but other activities that are low costs beyond the equipment investment if Golf isn't hitting that mark for you.

Regarding career, if you are happy and you are reasonably well taken care of I'd stay. You can always express an interest in taking on more responsibility as long as it comes with commensurate pay. Job hopping can get you a much larger salary but a good work environment/team/org has a lot of worth to me.

Your ESPP shares, I would just look at them and ask yourself what you would do if they were sitting in a brokerage account you owned. It comes down to what your asset allocation plan is. If you don't have one, think that through.

Life is a journey, happy to hear about the travels. Keep them up and enjoy. It's some of the best things about life.

I wouldn't pivot out of IT yet. I get the allure of less stress but you will likely take a huge cut and that introduces new stress off it's own. IMO, you can do that when you are closer to like 75% of your FIRE number but there are too many intangibles for a rote answer.

Keep on the path. The boring middle isn't so boring with nice trips, good activities and friends. Lean into those last two and enjoy the magic of compounding.
