Let’s be clear, taking a day off is not a sign of weakness. It will allow your body, mind and soul to a rest. To make this day achievable, schedule it and make a list of the things you want to accomplish. It can be as simple as taking the time to enjoy your hot coffee. Also, try to avoid everything that can distract you and use this day to recharge your batteries and to reconnect with yourself... in other words put your phone aside and mention it to those around you that if there is an emergency they can call you but other than that you won't be reachable. You deserve it, You need it.
