Suppose the 20+ years were all as a driver---would you make the move if it were offered to you today?
To the OP---Dragon has the best post yet. He is spot on when he says that anymore who solicits the advice of strangers on the Internet before making such a decision does not have what it takes to be a leader.
Take care before putting pen to paper.
I have what it takes no doubt in my mind. And clearly after two different center managers have asked me to be an on car they think so also. It's entertaining to see what drivers say when they have very little actual experience. I appreciate dragon chiming in.
