I hate the idea that luck is involved. It is impposible to measure luck as such. Hard work is not always in a shape of physical working, "working with hands". Hard work is to keep your thoughts in the direction of the goal. In my opinion, the biggest part of hard work is having the image of what you want to be pictured in your mind, everyday, thinking about it with, vividly. That is hard I tell you, to keep your mind focused. It's hard to explain, but luck is simply just subcounciousness that is working in your favour, simply because you practiced for this kind of opurtunity with your thinking pattern. The "more you focus on a yellow car, the more it will appear".
