You can benefit tremendously from a group physical activity, if possible, such as a team that trains together for an athletic event. The group spirit is uplifting for your nature, which tends to be introverted when left alone. And, having a goal can help shape your perspective about life, which can otherwise become obtuse and slightly pessimistic if you aren't careful. Enjoy yourself with friends who are physically active, if you can, and see what energy comes of it.
