I started with HTML in MySpace when I was younger but chose an accounting major to have a "safe" job at university. I spent hours in journal entries and Excel hell and had to learn VBA for a project. Learning functions and loops led me to learn openpyxl, pandas, and numpy in Python from books like Automate the Boring Stuff and Python for Finance. The best advice I received was to build things you're interested in because you will be more inclined to finish them. Best of luck!
