Linear Algebra is so cool

I loved linear algebra but I don't think everyone is mentally equipped to handle it. Calculus is easy to visualize as you can just throw it onto a graph and see what's going on. When people struggle with calculus, people struggle with the algebra involved and not necessarily the calculus. It's definitely something everyone can learn if they put in the effort. Linear algebra is falling more towards the highly abstract mathematics such as functional analysis, differential geometry and Galois theory. Math at those point are non-intuitive. I would be mad if I was not in a math-related major and linear algebra is one of my requirements.
