Cognition is your strongest design sense: the deepest layer of how your body perceives the world, running underneath thought and long before words. Everyone has one dominant channel through which the body gathers its most reliable information, and knowing yours means you can finally trust it on purpose instead of doubting it by habit.
This is a discerning sense, and it is precise. Once you have had real contact with something, you know your likes and dislikes with unusual clarity, and you are rarely wrong about them. The old phrase about something leaving a bad taste in your mouth is close to literal for you. When a deal, a person, or a plan sits badly afterwards, that aftertaste is accurate information, not squeamishness. When something tastes good, your body is telling you to go further in.
The trap is committing before you have tasted. The world rewards people who decide fast and sound certain, so you can get pushed into declaring on things you have never actually sampled, and that is reliably where you go wrong. Not knowing yet is not indecision in you. It is your deepest sense doing its job, holding the question open until you have had a genuine mouthful of the thing in question.
So give yourself the sample. Take the trial, the visit, the first small bite of a commitment before you sign up for the whole meal. Slow the moment of intake down enough to actually register the flavour: eat without rushing, meet a person more than once, test a decision at small scale before you scale it up. When you let yourself taste first and decide second, your discernment becomes remarkably reliable, and you stop mistaking a good description for a good thing.
