Where taking advice and living life intersect--and likewise diverge:

It always seems that whatever ideas I have in my head, my parents have other ones.
Whatever I think is a good idea isn't quite the wisest one to them. And where I struggle is that I can understand that my parents are more wise and experienced than I am. And therefore, their advice is probably really valid. But, how do I become wise by just listening? Isn't there some sort of do missing there? I mean, I could listen and do what they say--but what is wisdom if its not gained from experience. I only have the wisdom of the "easiest way to success" rather than "my very own" one.
I am probably the lest independant 22 year old I know. And I think it's because I've been taking advice all my life, rather than figuring things out for myself.
Right now I'm taking physics classes at Wayne State. My parents don't really think it's a great idea, but they're humoring me. I planned it so I could sub during the days, and get a part-time job in the evenings to earn money. I'm working on getting into districts as a sub--believe me, it's harder than it should be. My goal is to get another evening job so that I can make enough money to move out of my house. I mentioned this to my dad, and he immediately struck it down. "Moving out is not what you need to be focusing on while you're still in school." Which holds a valid point. However, I know myself. I am like a lamprey. A parasite, if you will. When given the means to survive off of something else I have no motivation or drive to do anything above and beyond exist. However, if a parasite wanted to live without a host it would most likely die. Survival of the fittest. When put in a situation where it is do or die, I thrive and I flourish. My sense of competition only arises when I'm in danger of failing. Otherwise I have no drive to pull ahead. It's how I've always been. At school, in sports, board games. . .etc.
What my dad doesn't understand is that as long as I am living with them in their house, I am never ever going to be independent. Because there is always someone there to pick up the slack. If there's no one there to unload the dishwasher for me if I put it off long enough, then I will do it right away. Because I have no other choice. If I have to pay a bill or lose any credit I might have, I will do it right away. Because I have no other choice. If I'm at home, somebody else picks it up and "puts it on my desk where I should see it." And I never do. I can't fall on my butt if I've got a fluffy pillow glued to it.
My dad doesn't understand this, because while I'm exactly like him in most ways, this way I am not.
My dad doesn't understand why I don't want to go back to the hospital and just work two 12-hour shifts making $12/hour instead of trying to find a night job a few nights a week making much less. He doesn't think that working extra days at less compares to working less days at more. Which he's right. But I don't think that extra money is worth having a job I don't enjoy as much as I could another one. He thinks that money does all the talking all the time, and I just don't agree. Probably because I've never had the chance to realize that I have to make what I live from. And as long as I'm living at home, I'll never 100% live off my own keep. Therefore, money doesn't talk as loudly to me as liking my job.
My dad said that when you're working for something, it doesn't matter if you like what you're doing or not--you do what it takes to get there. And this is another characteristic that I do not possess. Even when driving somewhere, I'm okay with taking back roads and other scenic routes. Because if I get to my destination and it's not what I thought it was, at least I have lots of places I saw on the way that might be better. I don't like shooting for a target, hitting it, and then thinking "okay, what now?" I'd rather shoot, and maybe hit something else on the way.
I respect my parents greatly. And they are both wise, and have great jobs and are in great situations. However, I have a feeling that if I let my decisions be their decisions then my life will not be my life. And I won't be able to teach my children anything but my way--which wasn't my way to begin with.
Freedom might be a gift. But independence doesn't come without sacrifice.
