But when I was a bit older I knew "I want to do something with computers", because my family had a windows 3.1 computer and I liked to play games on it. Of course at the time I had no idea what anyone even did with computers. I also had no idea that in the future every single job that exists would be "something to do with computers"
I started taking computer classes in high school which got me into programming, because I wanted to make games. This is a pretty common pipeline for Millennial programmers I think
After that I went to a local university and took Computer Science. Luckily I was just dumb enough to stick with it the whole time and get a bachelors. I say dumb enough somewhat ironically. Obviously doing a BSc in Compsci takes a bit of smarts, but I had friends who became convinced they were too smart to bother with a degree, and all of them who dropped out to pursue their own path without the degree are much worse off than I am now
Anyways, after my degree I no longer wanted to work in games. I wanted to work in embedded systems. Turns out there weren't many opportunities to work in embedded systems in my local market so I got into web dev. Like I said, not my dream job, but I'm very good at it and it has been a really successful career.
So I guess to summarize:
Yes I was pretty lucky to somewhat choose a direction when I was young, even if I didn't know more than "work with computers".
However the dream path still wasn't exactly a straightforward arrow from Ninja Turtle to Web Dev. At every single step it felt like I was compromising on my dreams.
Turns out that compromise can be really good though
I didn't grow up to be a Ninja Turtle
Have you ever eaten new york style pizza in a subway wearing cool colored clothes? You might be closer than you think..Although I may have to make a point of this sometime now, just for kicks
Carl Jung investigated this with his "puer-aeternus" (the child that was promised) and "senex" (old man) archetypes. A really interesting read, if you have time for that. In essence I think he advocated a balance, where one starts at childhood, becomes a cynical grown-up and then re-integrates his childhood fantasies back into his character, but now in a less naive and wiser way.
That's cultural bias right there. It happens only if you tell them to dream impossible big things. If you don't teach children that astronauts exist, they will likely dream to become their teacher or the janitor at school, especially the friendly, nice ones.
I now have red sport-touring bike and a beautiful wife so, mission accomplished?
