Gazing at caterpillars on a garden path does not generally lead to passing along your genes. Impatience and a craving for intensity does often lead to passing along your genes, I think the calculus is pretty straight forward.
However, your comment could be actionable in a number of ways, for example:
1. "You should embrace the intensity to make sure you reproduce."
2. "You should understand the source of that intensity as something that might oppose your goal of happiness."
3. "You should accept the biological inevitability of that intensity."
I'm partial to number 2. Even if the calculus of reproduction is straight forward, how that should inform your life choices is not.
So it’s basically saying that having a high sex drive leads young people to reproduce. Okay.
But if you mean low CNS arousal generally then I completely disagree, someone that pushes to 100% will out compete you if you never breach 50% assuming equal ability. If you and I both have the same capacity for strength but you are an intense person and I am not you will be the stronger one in the short and long term. Same goes for the intelligence question as well.
However modern society short circuits part this general behavior though and all bets are off though I still think it holds true. It is often not the best political or business idea that wins, it is the one someone is willing to push through. Human relationships are similar, an activation energy must be reached in order for mating to happen and someone with a higher intensity is more likely to reach that activation energy more often.
I think the concept was that someone overly driven might overshoot the ‘activation energy’. However, this conversation has grown insane in the mixture of vagueness and specificity.
