Very Humbling and Eye Opening

Going into the course, I was expecting a refresher course of what I reviewed back when I was a young man, but going through it, I underestimated what I would be getting from the course and now, I'm very much Humbled. Being placed into my place to know what the nitty gritty parts of the course was very humbling and very eye opening, it made me wonder if i forgot or missed anything else and took for granted as a young man.
I appreciate and love the ideas given by the course and hoping to use the lessons here as a refresher whenever I need it.
