Personality traits

I have often wondered what makes up a person's personality? Is it their environment or current circumstances? Maybe its in your genetic make-up? What influences you?, what drives you? Why is it that some children follow in their parents footsteps while others rebel and do the exact opposite?

I know of some people who are not of the "Elvis " generation, but love his music because their parents listened to it and it kinda grew on them. I know of Pastor's children who grew up in the church environment and became pastors or church leaders themselves. Then there is a pastor's child who wont even set foot in a church because he felt indoctrinated and and rebelled (not because his dad was a bad pastor or anything like that) but simply out of a need to be an individual ands carve out his own path in life. Then I thought what makes good parents have bad children? and vice versa? I have a cousin who has never touched alcohol out of choice and partly because his parents drank and partied all the time when he was young. I remember him driving them home from a party one night when he was 12 years old because they were too inebriated to do it themselves. lucky for him he is very tall and could reach all the pedals by then. Then you get children of alcoholic parents who learn form their example and become alcoholics themselves repeating the cycle all over again. One wonders when they have children one day, what path will they take?

I myself could not stand rap music and normally listen to classical or light pop, but when my daughters became teenagers they were all about Usher, Lil Wayne and Tupac. The music grew on me as i passively listened and found myself singing along and even putting it on when no one was around.
The other day I professed to loving Akon and singing along to Dirty Bitch -yeah I have no shame, the rhythm got me. I was influenced I could have resisted but yip the rhythm got me good.

Just random thoughts flying around in my head
