You don’t need a floodlight on the whole road. A flashlight on the next ten feet gets you home.

Headlights reach a short distance ahead, and that has never stopped anyone driving across a country. You do not need the whole route to start moving, only enough visibility for the next stretch, and more appears as you go. Insisting on seeing the entire road is usually a polite way of staying parked.

Choose the next ten feet and stop planning past them. One class, one conversation, one month. Check your direction occasionally, then go back to looking only as far as you actually need to.
