There’s only so much you can do in a week – or, according to Oliver Burkeman, in the roughly 4,000 weeks the average human lives. Oliver is a journalist and author of the books Four Thousand Weeks: Time Management for Mortals, Meditations for Mortals, and the newsletter “The Imperfectionist.” Chris and Oliver discuss the paradox of why change can only occur once we accept that we might not be able to change. Oliver also shares how life’s mishaps can become our most treasured memories and why sharing your imperfections is an act of generosity.
