I was interning at a small startup and made some financial models in Excel (using functions like index and match together).

At the time, I told a programmer at the company that I wanted to learn programming. He looked at my work and told me that I was already doing it. I didn't believe him because I didn't think it was "real coding". I thought he was just being nice.

My first "real coding" was a year later. I modified a few of the example apps from "Head First PHP & MySQL" (https://www.oreilly.com/library/view/head-first-php/97805961...).
