Twenty-two and unsure is normal. A lot of people who look certain are just better at hiding the search.

Certainty is partly a social skill, and some people acquire it well before they acquire an actual plan. The confident answer at a party is often a sentence somebody polished because the question keeps coming up. Their search is still running, just offstage. Being unsure at that age is the usual condition, not a failing the others somehow escaped.

Rather than asking people what they do, try asking how they ended up doing it. The honest version nearly always contains a few years of not knowing. Hearing that out loud takes a surprising amount of weight off.
