Evolution has left you with two basic drives - to survive and to procreate, but evolutionary biologist Rebecca Heiss, Ph.D. tells Joe De Sena how understanding those drives can lead us to overcome fears and achieve success. Fear, says Heiss, is an ancient signal meant to keep us alive, but most things we fear today are not life-threatening.  In this interview, she shares tactics to replace you A.N.T.s (automatic negative thoughts), to use triggers to heighten consciousness and to think like a Spartan.     As Heiss says - When life gives you lemons, bite down and keep going.     You can pre-order her book "Instinct: Rewire Your Brain with Science-Backed Solutions to Increase Productivity and Achieve Success " coming out in April.   “my entire field of study is based around understanding why we behave the way we behave based on these ancient stories. Basically I'm here to tell you that your brain is literally wired to survive and have sex. That's it. Two Worlds we live it right? Can I eat that or is it  gonna kill me?and can I procreate with that? That's what we’re walking around with most of the time. So how can we use that brain to maximize our efficiency in life?” ~ Rebecca Heiss, PhD FOLLOW SPARTAN UP: Spartan Up on Instagram https://www.instagram.com/spartanuppodcast/ Spartan Up on Twitter https://twitter.com/SpartanUpPod   CREDITS: Producer – Marion Abrams, Madmotion, llc.
