If you think from the perspective of the actual doer, it might be an admissible, perhaps even superior strategy to focus on "hard work" and "discipline" (where is the difference, btw?) and leave out "luck". But actually, when you're honest about it and take the perspective of an observer, you'd be foolish to focus on those things because you'd see that for every great success that worked hard to get there, there are at least a hundred "failures" (let's just take the conventional notions here) who worked equally hard. It's kind of demotivating though to have to realize that all your hard work is merely the necessary condition of success and that in the end it will be luck that will make the real difference.
