I do make wind turbine blades. I do write a blog. I do lead others. I do attend Grace Church. I do coach my son's basketball team. I do follow football. I do enjoy Doctor Who. I do read a lot of science fiction.
I am a father. I am a husband. I am a child of God.
In the end, life is about the "Am"s--the relationships we have--rather than the "Do"s, or how we fill our days. It is in the "Am"s that you find your purpose, your meaning, your joy.
Make sure your "Do"s don't take away from your "Am"s.
