Kant's was spectacularly uneventful. He was born, lived, worked and died in East Prussia. It is said that his daily schedule was so regimented that the women of the town could set their watches by him.

Human destiny is bound up in progress.
A rainy day is a wet day. The notion of wet day is already contained in rainy day. Synthetic statements are those where the predicate is not contained in the subject E.g. Tuesday was a wet day. The notion here of a wet day is not contained in Tuesday. It does not depend upon the evidence of experience for its authority.
