Focus under fire - Essential Systems
As you build your powers, and gain strength and take on more challenges, you will get to points where you are under attack from all sides. If this is the case you need to focus on essential systems and let go of the nice to haves. This probably means still focusing on getting enough sleep and showing up for exercise but maybe dropping studying Chinese or guitar. The rule of thumb is if the activity helps you heal or regain more energy than it takes to do it, keep it as it will make you stronger in a tough time. Otherwise, let it go while you focus on doing a great job on your challenges.
