Luck is irrelevant. Luck is a part of anything. New artists don't get a number 1 album without a bit of luck do they consider this into their actions no.
Luck is a part of everyday life not just poker, you can't control luck so there isn't any point thinkin if I was lucky. You can do better with skill hence all the win in poker players who don't depend on luck.
Maybe so, but people give to much credit for the luck in most of the things in life. If they see someone else who is very successful at something they say "oh, he is so lucky", without acknowledging the fact that that person probably worked very hard for it.
If they, themselves, fail at something they say, "ah, I got bad luck" as an excuse. Sometimes it might be the unlucky factor, but the majority of the times people will not see their own lack of perseverance, motivation or hard work.
A simple example I heard a lot is that during some exam they say that they got unlucky with the questions, while actually they did not study everything well enough.
That's why I used to say when people would wish me good luck: "luck is not a factor".
Now in poker of course a higher amount of luck is in play, but still, long term winners are just good. Period.
