The great American tradition is to honor and applaud those who go it alone—the Clint-Eastwood-John-Wayne heroic types. They didn't need anyone and were able to do it all by themselves.
Maybe in books and films it works that way, but I don't know anyone like that who's truly happy. I believe God created us for companionship (and it doesn't have to be romantic). In recent years, a number of films have been labeled bromedy—where two men join together for a common goal.
I'll tell you why I haven't wanted to go it alone. I need people and have always been aware of that. I'm a highly emotional person and my late wife was my anchor. So many times I was ready to move on in various phases of my life, but she was the calm one. She didn't argue or yell, but she helped me realize I was making an emotional decision and not a careful or reasoned one.
More than anything else, Shirley taught me that I didn't have to take the lonesome road by myself. Until her death, she was always there to hold my hand.
I no longer have her, but I have friends I can call or visit. I don't have to take that road marked Alone.
