I'd still take an online course even if most people don't finish it. I pick courses for specific needs: a single module, a practical skill, or a certificate for my CV. Short, focused lessons and clear learning goals keep me engaged, so I scan reviews and syllabuses first. I treat progress as flexible: learning at my pace, bookmarking useful units, and applying what I learn immediately. Social elements help when I need structure, but I don't rely on them.
