You know when you’re on an airplane and the flight attendants are doing their routine safety demonstration? They tell you that, if there’s an emergency, you should place the oxygen mask over your face first and then help those around you. I think this philosophy needs to be carried over into every aspect of your life.
Taking time to take care of yourself isn’t selfish — in fact, caring for yourself is what gives you the strength and energy to take better care of those around you. You are in charge of your life and health — make time to exercise! Stop the guilt and petty excuses. No amount of guilt or worry can change someone else’s misfortune or problems, so make time for you.
