So many problems are solved by having purpose in life. I've written a lot, but one possibility is helping lift humanity, finding joy through growth (learning, improvement) and unselfish service to others. Much revolves around my beliefs which seem like they would solve so many problems.

Somebody famous (Dickens or Tolstoy maybe?) said something like "All happy families are alike, and all miserable families are miserable in their own way". I think there is much to that: multigenerational unselfish service in a widening circle. Seeing what families' and/or cultures' traits allow them to persist over time is also interesting.
