Step-by-step explanation:
During an 18-minute Social PR day, it is recommended to schedule brief breaks for yourself throughout the day to increase productivity and effectiveness. According to best practices, taking even a ten-minute break every two hours can help you get more accomplished. This ties into the notion of separating work from your private life to maintain a healthy balance and increase overall efficiency, as well as the importance of updating your profile, staying connected with contacts, and setting realistic daily priorities. Therefore, every hour, you should take a short break, refresh, and refocus to maintain peak performance.
