But "lose" and "fail," as well as "win," are subjective. What counted as "losing" when you started may become "winning" by the time 5 years have passed, due to the change in perspective.
As a kid I wanted to make video games and (like many) this lead me to pursue software development as a career.
By the time I made it through college in the 90s I'd learned more and more about the games industry and learned that it's generally not a very happy place to work. Certainly not a place for me. So I chose a different path.
With several decades of following the game industry under my belt I feel I can very, very conclusively decide that this was the right call for me. Look at all the articles about game devs working insane crunch time and then being laid off as soon as the game ships, etc. I'm sure some enjoy it but it's very close to my idea of hell.
Simply avoiding that fate is something I count as a minor victory, and I've gone on to do other things.
It's madness for the parent poster to dismiss this sort of thing as either "failure" or "cognitive dissonance." I simply decided my original goal was not worth pursuing.
You set a goal (make video games) then gave up on it (didn't make video games), thus failing that goal. It isn't madness, nor is it rocket surgery. It's pure semantics.
I guess you have chosen a path that is not mentioned, "give up and try something new, but then pretend that isn't what you did"? "I don't call it giving up... I call it learning."
If you walked into your kitchen with the goal of making a sandwich and decided you wanted some oatmeal instead, would you call that a "failure?" Did you experience a "defeat?"
Most wouldn't say that you "failed" at making a sandwich unless you truly attempted to assemble a sandwich and were unable to do so.
Most would not consider me to have "failed" to become a game developer unless I'd made a true attempt at doing so: applying for jobs and failing to obtain one, or perhaps obtaining jobs and failing at those. Just as very few would consider me to have failed at becoming an astronaut or a professional hockey player, two other things I wanted to be as a child.
Strict definitions of "failure" aside, though, what I found really bizarre and bleak was the parent poster's claim that enjoying one's newly chosen goal+outcome to require an act of willful cognitive dissonance.
