Back in 2014 I found his lectures, and many of the other videos in the course very useful. Coincidentally, at the time of the course I was launching a software product and by applying some of the concepts learnt in the course it became something that is now bringing some $600K yearly in mostly passive income. So you do not need to go all the way in start up mode to get value from it. Reharshing the obvious is still great advice. We all have lots of blind spots.
