I can see a list of things that had little to do with one another that added up to who I am today. In chronological order...
1. My father left before I was born and my mother married a drunk:
Though my grandparents made my father spend a couple weeks with us most summers until I was around 17 I still have never really had a relationship with him. My step father wasn't the best of influences and did nothing that father's should do for their children so I was raised pretty much fatherless. I saw the damage that my father's drinking did to himself and our family and I decided very young that I didn't want anything to do with that. I also saw how he was to my siblings and I and decided that I wanted to be a better father than that, and I am.
I'm more sensitive due to only really depending on my mother and I've stayed away from alcohol and the party scene all my life. I've never had a drop, not even a wine cooler, and I don't plan to.
2. Family moved a lot:
Like Harls said, my family moved a lot all through the elementary years so I never really made those GOOD friends that shape your young life. It was just me and my brother and whatever random neighbor I was around at the time. I went to 4 elementaries in 6 years. I became very shy and only managed to make 1 really good friend toward 6th grade that lasted after that.
Being a shy and backward kid I stayed out of trouble and never got in with the "in" crowd or any others that would tempt me with the things teenagers do to get in trouble. Thus, I stayed pretty squeeky clean through my childhood and early adolescence.
3. My mom bought me Web of Spider-Man 81:
And thus, my insanity began. I turned into a huge comicbook fan at the age of 10 and still am nearing 20 years later. All my friends know me as the comicbook guy and I learned so much from comics while growing up, such as morals that my family never taught but Spider-Man did
4. I rebelled... by going to church:
Yeah, I'm a rebel, I know. I wasn't really rebelling but this was as close as it got. My best friend Brian (the one I met in 6th grade) starting going to church the summer between 9th and 10th grade (so between Jr. High and High School) and semi-forced me to go. The girls were cute, though I was too shy to talk to them, and I quickly made a couple of friends alongside Brian so I stayed and eventually became a christian.
My mother hated this because she couldn't stand penticostal churches and did everything she could to make me stop going but I fought her and I think this challenge led me to push harder and grow in my faith at the time. Being in church gave me friends, confidense, destroyed my stage-fright, destroyed my low self-image, and just all around made me stand taller. While I made the decisions to try and wait to have sex until marriage and to not drink at all... church encouraged those and modeled my other morals that's since become a staple of my being... such as not cursing, not smoking, being more respectful to people, etc. I would also later meet my future wife at this church.
So yeah, I think all of these things molded who I am until I was around 19 or 20 and I was pretty much developed as the man I am today. I've matured, married, and become a father but the root of everything I am began with those 4 things. I've just used them to adapt to the new challenges and blessings that I've been handed and I think I've turned out pretty well.
