Ask HN: What's a recent insight you had that changed the way you think?

In my experience, the greatest gains I've ever had in understanding the world around me have come in small "explosions" of insight. And a lot of times the substance of those insights I was likely equipped to understand months before they came to me.

Maybe having this sort of thread published regularly (monthly?) on HN could help us all bypass those latent periods we live through having no noteworthy insights.
