Can you identify the mistake?

Practice is the act of carrying out an activity again and again, to gain mastery over an activity. Psychologist Professor Anders Ericsson coined the term deliberate practice. Talent is important but it is the deliberate practice which makes an ordinary man into extra-ordinary person.

Deliberate practice is purposeful and systematic. You need to have a specific goal, stay focussed, avoid distractions, follow a regular practice schedule, and step up the game in terms of tougher challenges, enable correct feedback to build and gain mastery. Breaking down a task and improving small chunks through regular practice with immediate and correct feedback helps hone the expertise. Deliberate practice is learning by doing and stepping into an uncomfortable zone.
