Make a wise and conscientious decision about who you are going to hang out with and “do” life with! Being popular is never worth it. The wrong friends can lead you to make one mistake. This mistake can ruin your life and follow you forever.
Never say no to learning! Get outside with nature. READ BOOKS. Take that extra class. Take the harder class. Do the extra credit. It all matters down the road.
Work! Help your parents with the chores, the lawn work. A part time job is not demeaning. What a part time job can teach you about time management, interpersonal skills, communication will be valuable later on.
