Thanks! Indeed, software development seems like one of the most probable course (my bachelor was in CS, so that's not too far either) but I'd be worried to end up too deep in software development, with no "input" from what I learned studying maths. Ideally, I'd still put this background to good use.
BadCookie: isn't it possible to choose that as a short-term solution, and then slowly navigate to something closer to your strengths?
