I appreciate the post, and it would do good for most of us to understand how compounding works in so many things in our lives, also in relationships etc. But it isn't one thing vs. everything, there is also a balanced middle ground. A generalist might be interested in several things, and not care if as a specialist she could be "more successful", usually measured by an oversimplified metric, e.g. number of dollars or books sold. But this is a very good topic.
