The best years coming up? Can I do it?

I keep remembering how I would think that I had it perfect. 2 great kids, a wonderful wife, a good job, a great neighborhood...then BAM.

Now I'm struck with trying to make my future years the best I can. I owe this to everybody, myself included. What kind of father would I be if I cannot be joyful, to spread to Ani and Micah, not to mention Christy. God, please give me the strength and advice to make my future brighter than I can do all by myself.
