What's on my mind now?

I had a good chat with my two good friends just now. We chatted something that we don't normally discuss about. I find our opinions very interesting that's why I feel like writing what I think about it.We talked something about luck at first. Some say luck is like 'accidentally'. To me, I don't believe in luck but some people do. I think if everyone depends on luck, then there is no such things as 'hard work pays off' quotes. I only believe in blessings. Someone once told me that everything that happens in this world are all destined by God. So, it does not happen by luck or by coincidence. I, myself is a Christian. I see that what we have now and what we achieved before is not by luck but by hard work and also 'blessings'. Blessing is something that is destined to be given to you by God.I really want to confess it here that I hate my dad for believing in luck.I just don't know why and I don't really want to explain it. Another thing that I want to talk about is how to live like an 18 year old girl. I'm actually seventeen plus plus now but I'm going to be eighteen soon. Sometimes I really wonder if I'm mature enough to be an eighteen year old girl. How much knowledge or how much wisdom should an eighteen year old person have? I think a person is said to be mature because that person has that specific knowledge. A mature person would also know when it is the right time to play around and also the right time to be serious. Some people matures faster than the others. It depends on how much a person had gone through in life or what he had learnt. Nowadays, many eighteen years old kids still do not know how to be independent. Here, 'independent' means earn money to survive by ourself. I'm one of them who is still not independent.But, I have a friend who comes from a broken family and already started to earn money for a living at this age. He has to find money to pay his rental, for food,for transportation and for other expenses as well. He experienced it and he learnt it by desperation. To him, he felt himself is more mature than the other eighteen year old kids around him because he is different. It is not anyone's fault but because everyone's life is destined to be like this. So I personally feel, different people has different state of maturity.
