I've taken some mathematics and logic courses at a university level, and the thing I took from those experiences and apply everyday is the reasoning and proof structuring. Struggling through and coming to something of an understanding of the concepts of analysis (calculus) and algebra were a pivotal point in my intellectual development. As somebody for whom math has never come easily (and still doesn't), but for whom the beauty and wonder of it all was still enchanting, I'd heartily encourage any and everyone to learn some higher maths in detail. The specific results may not always be applicable day to day, but the way of thinking will stay with you. Good luck!!
