Practice doesn't make perfect, but it comes fairly close

Instead, it derives from engaging in sustained, intense, and deliberate practice in a particular area of expertise, in order to improve performance and cognitive thinking levels. Lead author Dr. Robert A. Baron says, "The same principles that apply to starting a new venture, such as self-regulatory mechanisms, and delaying gratification for a more long-term goal, apply to the process of getting in shape athletically. Through a sustained, intense effort someone can build the strength of their body or their business."

The authors show that across many fields of expertise most people work only "hard enough" to achieve a level of performance that is deemed "acceptable" by themselves and others, with no further gains. Through the principle of deliberate practice most anyone, the authors claim, can rise above this plateau to true excellence.

Entrepreneurs can acquire new capacities that can assist them in starting or running a new venture, or allow them to adapt to unforeseen circumstances, such as a drop in the economy, or PR crisis. These capacities include an ability to zero in on the most important information in a given situation, and more easily access valuable information stored in the long-term memory, or by increasing the capacity of short-term working memory. These factors also help secure a positive outcome: preparation, repetition, self-observation, self-reflection, and continuous feedback on results. These efforts lead to a healthy self-efficacy, or an individual's confidence in their ability and what is known as mature intuition.
