I recently bought "Courage is calling", the newest book from Ryan Holiday. I actually quite liked "Obstacle.." and "Ego.." having read them some years ago. But I do not know. I feel like I somehow has gotten older (scary thought :) ) I think the content in Courage is somewhat of the same type and quality, but I have only read a few chapters and it somehow comes off as trying too hard.
I am sure it is more me, than the content/author that has changed. But the original comment is so right in saying "You pay to be inspired".
