I think it is all a matter of perspective. You view yourself as un-lucky but nobody is lucky 100% of the time. There is a Russian saying: "You cannot get out of the water dry." We all go through life and there are good things and bad things happening to us all the time. We as people tend to focus and remember bad things. This is illustrated by the "Sandwich Rule" where it always seems to fall down with the butter part (good part).
So try to focus on the good things that happen to you in life. For example are you happy that you have your wife? Wasn't it a big good thing that happened to you? And your daughter?
But yeah success always involves a lot of hard work AND some luck...
