Am I ready?? Do I have a choice??

I have been thinking more and more lately about being a father. I know that no matter how much I think about it and how much I prepare, I will never truly be completely ready. I guess my recent experiences have made me think more about the next stage of life. I love being around kids, but, I worry that my body won't be able to keep up. Some of the best times of my life were spent being a counselor at C.F. camp, but now I am not sure I could do all the fun stuff I did then. The kids kept us going all the time and that is not to mention all the hard work preparing for the week of camp, fund raising and planning for the next event. I guess I am worried that my medical problems are going to prevent me from enjoying the creation of new memories with my own family. If I am to be a good father I must begin to repair my body now. The pending surgery is not much of a concern to me really, but it will definitely mark the beginning of a new commitment to repairing the rest of my body. I think making my thoughts public (sort of) will help. I have more of a reason to succeed if I make my intentions known. Not to say that I wouldn't try, but if I tell the world I want to be a better, more healthy and potentially stronger individual then maybe I can remember that I have made a promise to myself and I have to keep it. I don't think people would think less of me but I would think less of myself and I don't need that. I need to feel productive, I need to feel that I am more then a worker earning money to sustain my meager lifestyle. I am laboring to become a better man, physically, mentally, emotionally and in society. I am sure that weather or not I am prepared life will go on, I would rather feel happy and satisfied with myself then disappointed.
