I never believed in luck but determination. I can not impose my opinion on you, but I have seen very very few cases in my life that if someone wanted something in his life and he tried for it every day, he didn't get it. Unless anyone quits, he will definitely achieve it.
I have tried it, I didn't believe it before that if we keep trying we can achieve whatever we want, our past experiences make our opinions and what we believe in our life.
I have lots of experiences when I myself have achieved more than what I wanted by pure determination.
