We all need something in our lives to help us to feel complete. For me, it was my son and my two little girls. They are now raised and leading really great and successful lives of their own. Now, without my total first love, (flying) I know I would be completely lost. Having something to believe in and to push me harder to succeed at has helped maintain that balance now the kids are grown. Passion, addiction, obsession or just plain consumed...any way you stack it, I think (we) do this for the love of it all.
