Take one trip alone, even a short one. You’ll learn what you do when nobody’s voting.

In a group, every choice is a negotiation, and after enough of them you lose track of what you would have picked. You learn the compromise and forget the preference. Travelling alone removes the vote, so where you go and when you eat come back to being yours.

It does not need to be far. One bus or train ride, a day in a town two stops away, nobody to check with. Decide every small thing yourself and pay attention to what you choose when the choosing is unopposed.
