Taking care of your mental, emotional and physical health is imperative. It's mostly overlooked though and it shouldn't be. Set time aside for exercising, for fun, for "me time". Overall, good health coincides with the success of being an entrepreneur. You need the energy and stamina to maintain late nights, early mornings...working your 9-5 and your side hustles.
Self care is a luxury. Tend to yourself on a regular basis ok.
