Everyone has different parents, and according to Russell Kelfer's poem, "You are who you are for a reason" "the parents you had were the ones he chose, And no matter how y ou may feel, they were custom-designed with God's plan in mind, and they bear the Master's seal." That comes from the Purpose Driven Life which I'm reading for church, so it's a clearly Christian, but I think universal, concept.
One of my friends who I discuss this with and I talk about our parents frequently and how different they are. I'm a typical Caucasian. I have divorced parents and grew up with my grandparents and mother. My mom has pretty much ignored me when it comes to discipline and school. My grandparents focused on manners, but other than that, not much. My discussion friend, Hannah, is Chinese. Her dad pushes her to the extreme, over working her most of the time. She's in all the highest classes, takes clarinet lesson and practices, volunteers and takes a college course. It's too much work for her to handle realistically, but she does it, sacrificing sleep. Despite the lack of pushing from my mom, I'm motivated and have about the same amount of commitments and sleep schedule as Hannah, but it's self-imposed. WIthout her dad, Hannah insists, and i can justify, that she would just sit around all day and do nothing.
I take it that reason is based on your God given motivation level. In addition, I think the effect you'll have on your parents comes into play. It’s funny how kids don’t realize the role your parents play in your life because generally teens spend all their time trying to break free from parents.
