Can your friends influence your study habits?

Although I know I should be the only one held responsible for my lack of studying, I do believe that my best friends have had a horrible influence on my study habits. Both of my roommates never study. Ever. This makes it very difficult not only to concentrate, but to simply stay on task. If I try to study at home, they are distracting by being noisy and going crazy around the house. If I try to go somewhere and study, they try to convince me to hang out with them and tell me about all the exciting plans for fun that they have. Even though I know I shouldn’t, 90% of the time I give into their temptation. It would just be so much easier if they would set aside time to study too, then I wouldn’t be tempted.
