Our thoughts are transferred into our biology, which means generosity, service, and altruism make us healthier from the inside out, all while giving us more joy in life. Unfortunately, many of us go through life with a list of shoulds without truly knowing the why behind our actions. It can be a daunting task to seek meaning and purpose, but taking intentional steps towards this kind of clarity might be easier than you think.  Today on The Doctor’s Farmacy, I’m excited to talk to Simon Sinek about how to find your why to live a more authentic, fulfilled, and healthy life. A trained ethnographer, Simon may be best known for his TED Talk on the concept of why, which has been viewed over 60 million times, and his video on millennials in the workplace—which reached 80 million views in its first week and has gone on to be seen hundreds of millions of times. He continues to share inspiration through his bestselling books, including global bestseller Start with WHY and New York Times bestsellers Leaders Eat Last and The Infinite Game, as well as his podcast, A Bit of Optimism This episode is brought to you by Rupa Health, Thrive Market, ButcherBox, and Cozy Earth.
