Worrying about what you cannot control doesn’t give you more control, it just gives you more worries to sweat about — sometimes literally.
A key facet of resiliency is being able to recognize and avoid the stuff that unnecessarily takes up your energy.

If it’s out of your control, then giving yourself full permission to let it go is one of the most valuable things you can do for your well-being and what you’re trying to accomplish.
