I started by making myself a small personal website in the early 2000s, and introducing iframes because I was tired of copy-pasting the same navbar into each page. That led me to PHP to achieve the same thing with includes, and then the snowball effect started.
After more amateur and self-taught website work before uni, I then started a CS degree and was taught how to program for the first time: starting with Java, some Haskell, some C and more than enough perl.
The working world came knocking and I expanded my repertoire to include Python and any other language of the day.
