No doubt he was making this claim in a business context, but I wish it wasn't framed in financial terms. Our culture is already too obsessed with money, falsely framing it as the measure of the good life and of human worth. What an impoverished, boring, and frankly nihilistic and horrifying worldview.

That being said, pessimism/optimism is a false dichotomy. The reason is that both are willful attitudes of expectation on an emotional spectrum rather than rationally grounded and sober assessments of reality. The wise path is prudent (I don't mean "cautious"; I mean the classic virtue [0]). Prudence is rational. You can't be better than rational (genuinely rational; believing you are rational is not the same as being rational).
