Good comment. I would suggest if you get to the point where you want to really analyze your probability of success, you try one of the retirement modeling apps (I use and really like Boldin).
It was VERY eye opening for me in a good way. I have verified my results with several other sources. Its no guarantee of course, but I got some peace-of-mind from doing this.
I am 61 and still working at a tech startup. I love startups. I do not have to work any more (not wealthy due to an exit, but I have enough with normal savings and investments to stop now.) In my line of work (not an engineer, but engineer adjacent, lol) it is unusual for someone my age to be employed- it's a young person's game. But I am fortunate because I have attributes that many lack, including extreme tolerance for ambiguity (at work, not at life.)
I work because I like it. I like being around smart people doing smart things. But in a couple of years, I will stop working and just spend time lifting weights, practicing bjj and painting.
Thank you for linking to the thread from 3 years ago. Somehow I had missed that one. Good to see the game "The greatest paper airplanes" referenced there. I was the original designer on that game (and others) for KittyHawk Software.
