What i understand about life..

I always want to know more about life or even know better about myself. Somewhere, rather, i dont really understand what life is all about..To me, life is like happy go luck. Dont really think much what would happen to me in the future. Days goes by just like that, without even i notice it. As long i happy with what i do, i think it is good to me. What i understand about life is just one thing. Never give up. Life can some time hurt us. But we need to overcome it in order for us to live on. Like example, if we just broke up with our girlfriend or failed our exam. We cannot just hide ourself inside our room and keep on crying over that matter. What done cannot be undone right??..no matter how much u cry, the matter will still be with you. But unless, you find a way to handle it or to overcome it, you feel at least ok. My principal is simple. what i want in life, which is very hard for me to achieve, i will try really hard to at least think about doing it..
