The one who's been there

Already walked the road that scares you, so you don't have to guess in the dark.

Someone a few steps ahead. They've already done the thing you're nervous about, so they can tell you which fears are real and which ones evaporate the second you start. That's the whole value. You skip a year of figuring it out alone.

You don't have to know them well. Sometimes it's an older cousin, an old boss, a friend's dad. Just close enough to ask a real question and get a real answer.
