I grew up without a father. Well, sort of. My parents divorced (离婚) in the 1960s when I was a small child, and I stayed with my mother in Los Angeles. My father remarried and moved to a small suburb of Atlanta. For one month out of the year in the summer, I would fly back and spend time with my dad, so I had a father at times.
Further, I had a series of stepfathers who ranged from wonderful guys to alcoholics to dangerous individuals. Having lived through such experiences, I find it amusing when people say that children really need a father in the home. Well, if he is a good father and a good man, then I agree completely. If he is not, then the child might actually be better off without him. We don’t just need fathers — we need good fathers.
I feel it fair to say I ended up a very successful adult, at least that’s what people tell me. So how did I do it? I think it started with me having a bit of a chip on my shoulder. Normally this is not a good thing, but in my case it was rocket fuel for achievement. Not having a father in my life gave me something to prove, and it motivated me in an “I’ll show you” way.
I also tried very hard, even as a little boy to be self-sufficient. And that means I did not rely upon my parents except to the extent necessary. This kind of independence I believe is highly missed in this age of highly managed children with “helicopter” parents hovering (盘旋) above them constantly.
I also think I never wanted not having a father in my life to be an excuse for myself. We make and allow excuses constantly these days, but I just never felt that feeling sorry for myself was going to get me anywhere, I think if children can adopt such mindsets early in their lives it can be helpful.
