If you don't actually address the issue of whether Tim Ferriss is generalising from one example, all you're doing there is applying a fully general counterargument. Really, you should at least attempt to address such a concern, and only then ask "is that your true rejection?"

Also, you could probably have formatted the post better, because it's not completely apparent, especially to someone who skims through (which people will, because that comment was huge) that the whole thing following the link is a quote from a Cracked article (is it? I'm still not completely sure...) and what's appropriate in a cracked article that has "harsh truths" in the title isn't as appropriate in Less Wrong discussion, and it seems like you're being unnecessarily rude and aggressive as well as not exactly on-topic.
