If you can create something useful, its reachable audience (e.g., employers or customers) is essentially limitless--which greatly magnifies your reward. On the other hand, if what you're producing is mediocre, then you're in trouble, as it's too easy for your audience to find a better alternative online. Whether you're a computer programmer, writer, marketer, consultant, or entrepreneur, your situation has become similar to Jung trying to outwit Freud, or Jason Benn trying to hold his own in a hot start-up: To succeed you have to produce the absolute best stuff you're capable of producing--a task that requires depth.
