You have to learn to say no. I hate to miss things. I have to keep my priorities straight. School has to come first. There will be other times to see my friends.
Weekends are for friends, but during the week is for school.
I shut off the TV and leave the phone unplugged. With a lot of jobs on campus it's possible to get some studying done at work. I limit my work to 10 hours a week. I also think about what happened to my friends who didn't keep focused on their grades. It's something to look forward to when studying.
