One of the reasons why we tend not to build capacity is that we do not focus on the process. We are far more focused on using capacity than building it. That is what we mean by “getting ahead”.
But if you were to look back on your week of work, how much was done at a top level? How much did you do better than you had done before? Tough questions.
One way to change this is very simple. When you finish something meditate on what happened. The Sixers are introducing this into their practice routines. And it is a good idea. Allow the weight of what happened to sink in and pass on, so you can focus on why it was important and how you could build on what happened.
