When this is the case we want to err on the side of caution, especially if everything seems fine while doing the lesson, but then we have a big blow up or crash later on. If this happens then revisit the lesson and only do a bit of it, like 5 minutes. Then see what happens later. You can also try just listening to the lesson without participating with it, and see if there is the same kind of after effect. Once you internalize the principles of a lesson, you can also do a bit of that work without the audio – just a few minutes – and see what happens.
