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.
Well I don't believe something like success is determined by luck but luck is affecting our effort because luck won't appear if we don't do any effort, just like opportunities won't come if we only stay at home. Something like that will make some people who are unlucky give up quickly if they don't have good luck after a few tries since we know a lot of successful people out there become successful after a lot of tries and that is because they keep their effort going on.
