According to Ericsson, performance and enjoyment don´t come always together. I think that from all the factors of deliberate practice, this one might be the most controversial.
Generally, those who want to achieve a high level of expertise in any sport assume that deliberate practice is occasionally tedious and not very funny. For example, an athlete who performs any component of his technique analytically and isolated will never consider it as an enjoyable activity but by the contrary the athlete understands that it is needed to improve his performance, being eventually that reason the real source of motivation to keep practicing that way.
Ericsson does not leave any gap for innate talent, so then, does it mean that anyone could become an expert? That is, carrying out an adequate deliberate practice, anyone could become an exceptional tennis player like Andy Murray or Serena Williams, a sprinter like Usain Bolt or Shelly Ann Fraser or a football player like Messi?
