You have few weighty responsibilities to care for, just like you said and I quote "Managing groups and people have always been my dream, my vision, my passion." You've a very sensitive dream coming true because managing people isn't a child's play, you have to be very careful in your dealings, a good listener is what you've to be and above all is being humble & flexible but not compromising standards.
To whom much given, more is expected!
Take care James.
