The designer Stefan Sagmeister swears by the power of the sabbatical—every seven years, he shuts down his studio and takes a year off. His thinking is that we dedicate the first 25 years or so of our lives to learning, the next 40 to work, and the last 15 to retirement, so why not take 5 years off retirement and use them to break up the work years? He says the sabbatical has turned out to be invaluable to his work: “Everything that we designed in the seven years following the first sabbatical had its roots in thinking done during that sabbatical.”
