I often like to listen more than watching and reading. There is a tremendous amount of online lectures which can be listened to while working out or while running. Some Podcasts are also instructive. I would never have "read" GTD by David Allen if I hadn't gotten the audiobook, some topics don't interest me enough from the get-go (non-technical books) or have started to feel like a waste of time over the years (fiction) to really convince myself to sit and focus on the actual book.
