You need to take a break and have a breather. The Four of Swords shows that you are struggling with exhaustion and stress. As a result, your creativity and efficiency have gone down the drain. You have been doing extensive work and are overburdened. For now, take a break and enjoy a little privacy. The card also shows that you need to take some time off to recharge your energy. As you take this break, keep your mind blank and do nothing but relax. In the meantime, you can also meditate, do yoga, and spend some time with your friends. This will help you clear your mind and get rid of stress and tension.
The Four of Swords also says that you need to be silent and observe the world closely. It suggests you take time out and try to get away from the constant disturbance around you. Switch off your phone and turn off all other interruptions so that you can focus on your goals and your objectives. Take advantage of a quiet place or a place where nobody is around you so you can really concentrate on your goals.
