Here is a clip I from a podcast I did with @Lawrence_Sprung I think it will resonate with every parent. The moment that you hold your fist child in your hands changes EVERYTHING. It rewires your brain in an instant. You immediately think differently about the future. It's not that people without kids can't grasp long-term thinking. But there's a deep primal aspect to knowing your decisions will echo through someone you created. You stop optimizing for only yourself and start building for a timeline that extends past your death.
