So your school has decided to do start their own We Can Project. Amazing! There are a couple of things you should keep in mind throughout this process.
First, this is supposed to be fun. REALLY fun. So go for it. Be as creative as you want.
Second, this is not "school." There are no wrong answers. As long as you are doing something you are excited about, you're doing it right!
Third, you do not have to do everything yourself. Be sure to ask questions and get your friends, and parents, and neighbors to help. The more people involved, the better. Last but not least, do not give up. Sometimes, doing big things can be a challenge. But it will be worth it. So learn a new language, or instrument. Join a club. Start one. Build something. Volunteer. Donate. Make art. Make a mess. Clean up a park. Whatever difference you want to make, You Can!
