The myth of the rugged, independent, self-made man is as antiquated as it is wrong. First, because it’s defining feature is “manliness.” In my experience, women tend to be much better at getting shit done. Observe any mother.
Second, being “self-made” fails to address current realities. You, as an individual, are not scalable. You are not accountable. You only have one perspective. You only have certain skills. You cannot keep up with the pace of innovation. You only know what you know.
