My father was absent most of my life. He lives in another country and I can see him only once in several years. If he was with me during childhood it would have made a huge difference in my life.
Because of a lack of a father figure I have self-esteem issues, kyphosis and low self-discipline.
As much as my father was capable of granting me a good life, he was also capable of ruining my life.
He ruined my life by avoiding responsibilities of a father and my mother had to bear all that burden until I grew up. My mother can't be both a father and a mother to me.
My mother doesn't have the authority that father has. Authority that I didn't receive from my father.
I didn't say I didn't make mistakes too and that I am sinless. Everybody is the blacksmith of their own happiness and everybody pays for their stupid mistakes from youth.
But our parents can make a huge difference in how our life turns out.
I grew up without a father. First time I (knowingly) saw him I was 10 years old, and the last time I was 17. In between, I possibly saw him a dozen times at most, but likely rather less.
I never missed having a father, or there being a father figure in my life because there never had been one, so I had no idea what was missing, or indeed that anything
was missing.
I also think that for any of us that grew up in what were then often referred to as 'broken homes' it is impossible to know what life would have been like otherwise. In fact for me, given that the one parent I had was highly toxic to me, having two to deal with instead would likely have made life a lot worse than it already was, but in truth I just think it is very easy to blame others, or unfortunate circumstance, for our difficulties rather than simply accept what we cannot change, and then look for ways to overcome our problems and build on our own strengths rather than others' weaknesses.
As such I don't think others have greater control of our outcomes than we do ourselves, even if it takes us a while to discover that.
But there are a couple of things I'd disagree with specifically: "Because of a lack of a father figure I have self-esteem issues, kyphosis and low self-discipline." - I seriously doubt that the lack of a father figure would cause excessive curvature of the spine.
And "My mother doesn't have the authority that father has. Authority that I didn't receive from my father." - Parental authority is not a gender thing in any sense. Children need boundaries and rules, and whether mother or father or both, parents have a responsibility to impose that authority for the benefit and welfare on the child. Absent your father, that responsibility fell to your mother, whether you (or perhaps she) appreciate that fact or not.
You are right though, that parents can make a huge difference.... though not in how our lives
turn out, but in how we approach 'being the blacksmith of our own happiness', as you so eloquently put it.
