Recently I have had numerous reunions with Uncles from my extended family. Some of them are successful businessmen for decades. They built their business from nothing and are living quite a comfortable life now. We had long conversations about life in general, including their key to success. I knew very well that they have been hard workers ever since I had a memory so I would contribute their success to endless efforts. However, one thing they had mentioned in common was luck. They believe pure luck made them meet and grasp those opportunities and become successful rather than their smartness and efforts. I've thought about this before and couldn't agree with this more. They've set very good examples to me, including my father, and now I tend to focus more on work itself consistently and let luck or fate takes the rest.
Work hard with all your might, and after that leave fate to the results. I don't think it's luck, because realistically and logically it has also been seen that someone who works hard and wholeheartedly in doing his job, will always be rewarded for his hard work. So actually what you are talking about is not just luck, because your parents and your uncle have worked hard at doing their jobs. So it is certain that the possibility of getting success is very high. And what I absorbed from the post you made, actually your argument or story seems to lead to a feeling of surrender when you have worked hard, and surrendered the results or not to those above and in my opinion that is not luck but resignation.
