There are many important keys in this section, but the most important key, to me, is prioritizing teaching online and your personal life. You must manage your time properly and set strict boundaries. It's important to ease your workload and stress levels. A few things to help with that are; Organization (managing your workload), Discipline (blocking certain times of your week and weekends for responding to learners), Flexibility (selection of appropriate technology for your online course), and Distinguishing between work and personal life (set boundaries).
