Have you eaten? Before giving up, make sure you’ve tried your best. Have you eaten within the last 3 hours? Are you hydrated? Have you showered in the last 24 hours? Have you connected with a friend today? Have you given or received a hug today? If the answer to these, or your own checklist items, is no, stop what you're doing and rectify that. Whenever you are feeling the blues, it's probably because you have not fulfilled enough of your best person requirements.
