Consider how many activities you do outside of school. Remember that school needs to be a priority. It's great to do extra things--as long as they don't rob you of needed energy for learning. If you feel like you are too busy, ask your parents if you can cut down to one or two favorite things. You may try one activity one semester (i.e. being in a play) and something different the next (playing a sport). We often feel we have to do everything at once at once, and that can wear us out!

People often feel as if they are too busy.
