Even when doing a “beginner” course, I often find I gain a new understanding. It might be something explained slightly differently than I heard before or some tool I’d not seen before, or a technique or way of doing something that I didn’t know. And it never hurts to practice the basics because the more we practice the basics, the better we get overall. So try to find one thing you can latch onto that you didn’t know before. Might it be different, yes… but that doesn’t make it any less valuable in the long run.
