> In sum: DP simply has too high a bar to clear. Want to do DP? Well, has there been a few decades of pedagogical development in your field so that you can be coached like with chess or math or tennis? NO? Ok, you're tough out of luck. No DP for you!
I actually read "The Cambridge Handbook of Expertise and Expert Performance" and if i recall correctly it's not that simple, , Expert practitioners can develop themselves better methods (it is argued the reason world records keep getting broken is not because our genes become better but because of better training methods ) , the main thing about deliberate practice is detecting points you can improve (e.g. failing to answer a coding question in a job interview), developing a method to improve the sub skill (trying at home with less stress and more time, going over a piece of knowledge you forgot, e.g. how BFS works), going over "socially accepted good enough" to "the best you can be" (e.g. you might fail some interviews and think maybe the interviewers don't like you, or you could double check your answer and find better solutions which might help if you will interview to more demanding companies such as facebook or google).

There is another interesting book called "the psychology of problem solving" (see http://www.al-edu.com/wp-content/uploads/2014/05/Davidson-St...) where Ericsson argues iirc that deliberate practice is a form of problem solving.
