18. Skip hitting a fast-food joint and pack a picnic lunch for you and a co-worker to enjoy one day.
You probably eat lunch at your desk or in the dingy break room every day during the winter. So take your meal outside once it gets warmer and enjoy all that summer has to offer. For added effect, throw in some fresh fruits, vegetables, and juices to make sure your lunch hour feels like a week-long vacation. You can have a little slice of paradise every day if you do it.
