Solely!? That takes some doing.
You never read a non-fiction book, or at least you never believed one.
You never had a history lesson in any medium. In fact you have no knowledge of history, because necessarily you weren't there for the first-person experience.
You never used a map or verbal directions to get where you were going. You found the way by trial and error aided by such memories as you had from having traveled the same routes before.
You never checked the weather, insisting on stepping outside or waiting til you got there to see for yourself.
How do you manage?
