text: Stressing doesn't help you, it does the exact opposite. Stressing about that after school activity you have to participate in doesn't help you when you get home and have to do homework. Homework is already hard enough not being able to focus, but with this new activity you have to do, it'll be harder. Having harder homework due to stress can cause you to get bad grades, and could lead to you failing that class. Most likely when you get home from practice, or another activity, you're tired and don't feel like sitting down and doing homework. But not doing your homework, can cause you to fail that class, which possibly means you get kicked off the sports team, and having to do better in school.
