Moderation may work in some cases, but if something is not bringing you joy, why are you keeping it around? Get rid of anything that robs you of happiness. And don’t get rid of it gradually—get rid of it cold turkey. Make a list of things that zap your energy, slow you down, or leave you feeling guilty or remorseful, and then simply cut them out of your life. That may not be easy to do, but your increased joy and feelings of well-being will be worth it.
