Childhood Struggles

I am almost 60 years old and have started looking back at my younger years, especially ages 12 to 32. I believe my frontal lobes came online late, and I developed many strong attachments to girls during that time. I think I fell in love maybe 12 or 13 times. (Ask me about singing to a girl over the phone or castrating pigs with a girl's father just to be seen.) No one ever spoke to me about my brain, and I realize my brain made me a real asshole. I was hurt, and other people were hurt. I take responsibility for my own actions, but is it also OK for me to harbor a little resentment about my education? Would I have listened if someone had told me about it?
