Basic education and skill. Sports immediately came to mind. Most football players lack basic education, but thanks to their skills, they can earn money most people can't. A person can also train themselves later. Skills seem more important to me, but both are possible, but sometimes you have to sacrifice some things from education to improve your skills. In such cases, if I had to choose, I would focus on skills.
I don't think school education is as important anymore as it was in the past.
The same goes with boxing and basketball. Or let's all just say that in the sense of all sports. It's hard to be an athlete and these people are sacrificing their education for them to be trained and be better at their skill. This only proves that it's not always the educational certificate that we earn could make our lives better. But our skills will also do that for us. As for these sports professionals, these are the few people in the world that have a top notch skills on the respective sports that they are part of.
And not only skills but pure talent too.
