I agree with you, and also with the GP. Given this is HN, I read that comment as assuming an entrepreneurial disposition, one wants to "change the world". It's easy to imagine how one might want things to be, imagine steps to achieve that, and then crash hard into reality. Regardless of intelligence or diligence, the future is fundamentally unpredictable. I take the GPs point to be that you'll do better in your goals if you are able to pursue them with a measure of naivete versus dwelling on your best expected probabilistic outcomes which are likely to become more pessimistic as you gain experience. This is reflected in the common story from successful entrepreneurs: "if we knew how hard it was going to be we never would have started". That said, I also appreciate your point about perspective. The ideal is to be able to leverage all your knowledge, instinct and willful drive, but without an emotional attachment to an outcome. Walking the tightrope between apathy and frustration as it were.
