It seems as if I've been using a different definition of deliberate practice to the author. They seem to imply that deliberate practice requires a regimented study program, but I've always seen it as "identify the things you are weak at and drill those things, rather than repeating tasks you are already comfortable with". Is there a name for the type of practice I've been doing?
