• Work along with me in the videos.  Don't watch passively - join in!
• You can always pause or rewind to reflect on key points.
• Don't expect everything to make sense straightaway.  Often we need to go back to a lesson at least once to really understand what's going on - that's normal.
• If you're struggling with an exercise, you can always go back to the lesson, or forward to the solutions - it's not giving up or cheating, its part of the learning process.
