Ideas of simple teenage goals?

I like the leave an inspirational note in a library book. someone gave me a book last week and she left an inspirational book mark for me. I thought that was great. You can type random acts of kindness in the search answers feature on the site, there are tons of great ideas. I had a neighbor who mowed my lawn for me once. That was the nicest thing anyone had ever done for me. My husband had just gone to war, I was working 16 hours a day with no days off and I came home from work one day and he had mowed my lawn for me. I cried it was so thoughtful. When I was little we would cut flowers from my grandfathers gardens and take them to people in the nursing home that didn't get many visitors.
