It's very true. There is a telos to existence that we are in denial of, people drifting through life wallowing in sadness, consumerism, hedonism, chemical dependency, looking to 'find themselves' or 'figure out how to adult,' etc. etc. etc.

We've forgotten this basic lessons our grandparents took for granted: humans weren't meant to live this way. Get married and have kids, it really is that simple, let the next stage of your life begin. Once you stop fighting the current you find your brain has all sorts of new pathways to grow and mature, all these tools left to rot become useful and important, and you don't have an eternal hunger that is never filled.

So much of modernity involves fighting nature tooth and nail, with only misery as the result.
