All difficult questions have answers at a higher level. Problems at the same level are hard to solve with the same level of thinking. Only when your own level of understanding improves can you successfully solve lower-level problems, just like a college student solving elementary school math problems. Jobs didn't solve the problem of feature phones, but he made the problem of feature phones irrelevant; Musk didn't solve the problem of traditional cars, but he made the problem of traditional cars irrelevant; Zhang Xiaolong didn't solve the problem of instant messaging in the PC era, but he made the problem of PC instant messaging irrelevant; Zhang Yiming didn't solve the problem of portal news, but he made the problem of portal news irrelevant. #BNB #Strategy增持比特币
