I am 35, married, raising two kids (from my wifes previous marriage, she has a third who lives with her ex). I am General Manager and Chief of Staff to the President of a professional football (soccer) team. I am currently reading GTD but prior to that I read up A LOT on it via blogs and various web pages. While I still have not finished the book, I can say that the vast majority of my "tasks" are "follow ups" and "waiting ons", I oversee a lot. While there are certain responsibilities that I am directly involved with, most of it is supervision. I keep the schedule for a man who is very busy running two businesses (the team, his other company). I am hoping that GTD will allow me to put things in a timely and efficient order. I have always been one who adapts what is learned to apply to my personal way of working/ thinking, and was glad to read how many have taken bits and pieces and worked them into their lives.
