Never measure the height of a mountain until you have reached the top. Then you will see how low it was. — Dag Hammarskjöld

Insight: We spend so much mental energy worrying about how hard something will be before we start. The mountain looms enormous in our imagination—the project feels insurmountable, the conversation terrifying, the change impossible. But here's what actually happens: once you're moving, once you've taken the first real steps, the obstacle starts shrinking. Not because it was never difficult, but because you're no longer staring at it from below, paralyzed by its shadow. This flips something we usually get backwards. We think confidence comes from believing something is easy, but it actually comes from discovering—through the doing—that we're more capable than we thought. The mountain was real. The difficulty was real. But our imagination had inflated it into something monstrous. The low point Hammarskjöld mentions isn't sarcasm; it's the honest perspective you earn by surviving what you feared. The practical takeaway is almost rebellious: stop trying to assess the true difficulty of something. You can't, not really, from where you're standing now. The only measurement that matters comes after you've climbed.
