In other articles I&#x27;ve read about deliberate practice, the other elements include:<p>1. Maintaining a difficulty level that is just barely out of your comfort zone: not so hard that you flail wildly, but not so easy that it&#x27;s trivial.  This is touched upon in the article, but presumably &quot;deliberate&quot; practice also deliberately adjusts the difficulty level in response to performance.<p>2. Mindfulness while you&#x27;re practicing.  The description of &quot;purposeful&quot; practice in the article mentions seeking out errors and correcting them after the fact.  The descriptions of &quot;deliberate&quot; practice I&#x27;ve heard mentioned paying careful attention to your performance <i>while you&#x27;re practicing</i>, so you can instantly correct or rehearse trouble spots.  (And this requires a corresponding attention to the difficulty level so that you can spare this attention to avoiding &amp; fixing mistakes.)
