Coming back to the original topic about luck, IMHO, luck is at least 50% of success, but the other 50% needs to be attributed to perseverance, hard work, and risk taking.
An example would be the many immigrant “boat people” who risked their lives to get to America. The luck part is that they didn’t get killed while trying to escape. But, it takes the hard work to save up the money to get on one of those boats. It takes perseverance in trying and trying again if the first time fail. It take risk taking, knowing that if you get caught, you’ll be put into concentration camps and possibly get killed. So, sure, luck is part of it, but sometimes, you have to be willing to put yourself into a situation that can take advantage of that luck.
