Growth is more or less continuous – as we refine our technique, we get better gradually over time. But growth isn’t the only type of improvement.
If there is a problem, a specific barrier to higher performance, solving it will not be a gradual process. When the problem is solved – either through an insight and a change in practice, or through outside assistance – performance takes a dramatic leap.
When you are considering your own practice, or the practice of someone you supervise, think about whether the greatest growth will come from a focus on problem-solving, or from refining existing techniques.
