Brad Stulberg writes and teaches about mental health and well-being, and is author of several books, most recently Master Of Change: How To Excel When Everything Is Changing — Including You. Stulberg dives into the science and some of the ancient wisdom behind change. The ancient Greek philosopher Heraclitus, who wrote about the nature of reality and its relationship to change, famously said, “no man ever steps in the same river twice, for it’s not the same river and he’s not the same man.”

“There's one tragedy that none of us can avoid, which is that the things that we love are going to change,” says Stulberg. “And yet, in spite of it, we can still trudge forward with a hopeful attitude because this is the life that we have, these are the cards that were dealt, and it serves us no good to despair.”
