How have you betrayed your younger self? (Please read criteria in OP before posting!)

For all those reading less and less as we grow older and our vision loses focus (not to mention the curious, particular, personal handicaps and burdens we all carry): you are not alone.

Do you mean that at one time you would have opposed gender affirming surgery for anyone? I don’t know that my daughter, who is also a trans woman, would have had an issue with it at any point in her life; the older woman who often greeted us at the door when we got to church was trans, and our kids thought highly of her.

When I was young I envisioned a life of travel and adventure, and whatever work I’d be doing would be outdoors, in conservation or somesuch. My first career was a mapmaker, so that had me on the right path - a lot of fieldwork. I would never spend my days with my fingers tapping a keyboard and blinklessly staring at a screen.

Lo and behold, I got married, got a dog, got a house, got a couple of kids and a SAHM - the trappings of a solid suburban existence - all looking to me for support. As a matter of convenience and security I stepped into roles and jobs that paid more, but we’re more and more desk-bound. And that’s how I spent the bulk of my working life - as a cubicle-dwelling corporate drone doing unfulfilling and forgettable work. By hey, I took care of my family and home.

Now that I am rolling-up on retirement (hopefully within the next 3-5 years), I have started to travel more, with the resources and bits of time to do it as rough or as comfortable as I want, so the there’s that (even though with less vigor). Being active and outside was in me all the time, but smothered by the shackles of responsibility. Now that many things have eased I am getting back to me, but my younger self would have been shocked at how I became just a paycheck and drifted through the last 25 years.

When I was a kid I said I wanted to quit school at 16 and be a ditch digger. Instead I had a long career as a librarian.
