"You won’t find many quick fixes…(to mindset)…but there is one way to immediately boost willpower – slow your breathing down to four to six breaths per minute. That’s ten to fifteen seconds per breath—slower than you normally breathe, but not difficult with a little bit of practice and patience. Slowing the breath down activates the prefrontal cortex and increases heart rate variability, which helps shift the brain and body from a state of stress to self-control mode. A few minutes of this technique will make you feel calm, in control, and capable of handling cravings or challenges."
