How do I change careers when I have no idea where to start?

You want out, and you have no map for how to get out. That combination, strong pull, no plan, is disorienting, and it can keep you stuck for years. But wanting out is information. It means something in you has already decided; you just do not yet know where to point it. You do not need the whole path before you move. Career changes almost never happen as one clean leap; they happen as a series of small tests. The goal right now is not to pick your final destination. It is to learn enough to take the next honest step. So start with exploration, not decision. Find one person who does work that interests you and ask them how they got there and what it is actually like. One real conversation teaches more than a month of wondering. You do not have to know the whole way out. You have to find the first door and open it.
