What are two of the important aspects of body language I want to improve the most when having an online meeting/class next time? Why?

The first aspects of body language I want to improve is eye contact. When I was speaking in the meeting, the teacher often told me that I should look at the camera.But looking at people talking makes me feel less confident, so I have to overcome this difficulty slowly. 

The second one is to pay attention.When the teacher is in class or the classmates are reporting, I often have trouble paying attention all the time.  I am easily influenced by things outside of class, such as sounds from the window.I think next time I can turn the meeting voice louder to avoid being distracted by other things.

 I think more and more people are using delivery apps because of the coronavirus pandemic. There are so many people in quarantine every day, and delivery apps has become a daily tool. In addition, people are lazy these days because of the development of  technology. As long as you pick up your mobile phone at home, you can eat something far away from home without going out. So even I also use delivery apps a lot.
