I want to highlight your comment. I don't necessarily think there is a ton wrong with this blog post, and major kudos to the author for his success. I would just like to point out that trying to transfer these techniques into 90+% of the rest of the population would probably not result in their success.

I'll use myself as an example. I've heard the bromides of "Get out of your comfort zone" and "push through", yada yada, many times. And I indeed have gotten out of my comfort zone many times. But I've found that often times I have extreme stress reactions, sometimes bordering on panic, when I get too outside my comfort zone. I find this especially the case where I take too much on at once - I have a poor ability to prioritize and just "let things go" that aren't important. I wish this weren't the case, but after many cases of trial and error I've found this is how I am. It's not that I'm not capable of growth and change, but I'm quite positive what has worked for this guy will most definitely not work for me.

In general, be very careful of following any successful person's advice on how they became successful. There were a whole lot of other circumstances, innate gifts, and a lot of luck for any specific person that won't transfer broadly.
