Do you need to make an important decision? Get a good night’s rest. Do some aerobic exercise and eat a ‘good square meal’, as my mother would say.
Your brain’s prefrontal cortex, which is responsible for solving problems and making decisions (as well as other executive functions like abstract thinking, managing your emotions, planning, and regulating your behaviour) needs to be exercised, fed, rested and watered to work properly.
Located just behind your forehead, your prefrontal cortex also helps you learn, adjust and react to changing situations, and concentrate on your goals. So don’t make any important plans or decisions or hold any difficult conversations when you’re feeling hungry, thirsty, tired or stressed.
As a leader, you need to make calm and well-reasoned decisions and control your emotions and to do that, you need to take care of yourself with proper rest, aerobic exercise and nutrition.
When are you at your freshest? That’s probably when you’ll be most creative, able to deal effectively with challenging situations and make sound decisions.
