Keep your focus where it belongs which is on your life purpose. You will have enough of what you need to put it out into the world: enough money, enough time, enough energy and enough ideas.
Being overwhelmed with work does not make you more important or more necessary or more desirable or more marketable. It makes you miserable, unfocused and frustrated that you cannot get it all done.
Stop equating busyness with worthiness.
Stop saying yes to stuff. Say yes to your family and your relationships. Have the courage to say no when it takes you away from your life purpose.
