As an undergrad student I must agree, preparation makes a big difference. It's so hard sometimes to avoid distractions but I always bring myself to focus again by reminding myself on why I started studying in the first place. Thank you for this video which pointed out challenges that I can relate to and solutions that can work. One thing that helps me is getting reward snacks around and preparing enough food beforehand, so that I always have something to snack on. I find that I get hungry a lot when I'm studying. 😄🙌Thanks again for an awesome video. 😎👌💯
