I will discuss what deliberate practice is and isn't, and debunk a few myths concerning talent and expertise.

How do you develop expertise? Peter Norvig writes: "The key is deliberative practice: not just doing it again and again, but challenging yourself with a task that is just beyond your current ability, trying it, analyzing your performance while and after doing it, and correcting any mistakes. Then repeat. And repeat again."

For a developer, deliberate practice means trying new things, trying old things with a view to making them fresh and trying to move from accidental practice to intentional discipline. Deliberate practice improves technical agility through increased self awareness.
