Some things that courses can teach you that build your human capital are

Knowledge of your strengths, weaknesses and interests that helps you decide what jobs you're most suited for. For example, if you're thinking about becoming a lawyer
Subject matter knowledge that's directly relevant to your future work. For example, if you're going to be a biomedical researcher, a biology course might teach you prerequisite knowledge for your future work.
Skills that you’ll use in your future work. For example, if you’re going to be a lawyer, a philosophy course might teach you how to analyze arguments — a skill that many lawyers use on a regular basis
