I had a similar experience growing up as well. At age 8, I learned QBasic (on an MS-DOS / Win 3.1 system). At age 13, I learned C, and wrote a lot of code in it as well. (I used to write tons of C code up until around the middle of age 17. I had grand plans for all sorts of glorious software projects.)

But then, at the middle of age 17, a certain mild depression ("dysthymia") set in, and I lost a lot of hope, inspiration, and motivation. And now, I'm 31, and I've accomplished very little of my teenage dreams (even though I still hold/aspire towards those software dreams). I might be "successful" in society's eyes, with software engineering jobs paying in the ~200k range (which is not really that impressive, as I have many friends making in the 300k to 400k (USD) range); but in my own eyes, I still feel very much like a failure.

The depression or dysthymia had a crippling effect, that made a lot of dreams hard to accomplish. My 2021 New Year's resolution has been to overcome it my mental issues, and live life to the fullest.
