A positive attitude can go a long way in stressful situations
Your mindset and attitude affect your work as an online student. Focusing on the positive aspect of a situation takes less energy and is less stressful than worrying about the negative components. Instead of focusing on a negative outcome, like receiving a bad grade on an assignment, visualize yourself succeeding. This will both motivate you and leave you with less stress.
Remember, you may not have control over every situation but you do have control over your attitude.
