Example paragraph:

One of the healthy habits I follow is doing morning exercise. I started this habit two years ago after reading an article about the benefits of physical activity. Every day, I wake up at 6 a.m. and spend around 30 minutes jogging around my neighborhood. It helps me stay fit and energetic all day. I also drink enough water and eat more vegetables and fruits. I avoid junk food because I know it’s harmful to my body. These habits make me feel more relaxed and confident. In my opinion, keeping a healthy lifestyle is very important, especially for students like me who need both physical strength and mental focus to study effectively.
