I'm certainly guilty of taking the lone wolf route. When I know how to do something, I just work on getting it done. Part of this is due to school group projects when I was growing up. Too often, I not only found myself doing the bulk of the work, but often having to fix the elements that my group contributed. I've often been accused of thinking that I am better than others, and I have to say that those experiences really reinforced that idea.
However, I miss too many things when I try to do it all on my own. I don't take into account ideas and options which would never occur to me. Instead, I find myself trapped in the ruts of the "perfected" ways of doing things that I had come up with. Often, I do not realize how much trouble I'm in until it's too late.
Thankfully, I have family and friends who have helped me through those difficult times. Even when they are not near enough to help, I have my God to call upon. One way or another, I am lifted out of the hole which I had dug for myself.
