May I suggest not worrying about the "best" way to progress and just worry about "whether" you are progressing? The best can frequently be the enemy of the merely useful. It is far more important to progress than it is to progress optimally.
As far as lessons, I'm quite convinced that there is no best. There is only best FOR SOME and then only at certain times in their lives and only if the purposes coincide. What works for me may not work for you, and so on. That doesn't mean we shouldn't discuss what works and doesn't, but it does mean that if you read something is the "best" and doesn't work for you that you shouldn't let that frustrate you.
