Don’t worry about what your first programming language is. Every language has something to teach you. If you continue on in programming for any length of time, you will learn many languages. There will always be new ones, too.
It helps to learn languages that come from different paradigms or approaches to programming. This gives you a better sense of what a language can be; what it can do for you. There are languages with a lot to teach, and they’re often the ones popularly considered “difficult”.
Learn Haskell. You might never use it professionally, but it will greatly improve your understanding of what programming is. And no, you don’t need to be a mathematician to use it. (Recommended text: Graham Hutton’s Programming in Haskell, second edition.)
Learn SQL. You will use it professionally, sooner or later, and you’ll be better off actually understanding your database than trusting libraries designed to hide your database from you.
