Nash 's Key Ideas from Peak: Secrets from the New Science of Expertise
by Anders Ericsson, Robert Pool

• We all follow pretty much the same pattern with any skill we learn: We start off with a general idea of what we want to do, get some instruction (teacher, a book, or a website), practice until we reach an acceptable level, and then let it become automatic. 
• But once you have reached this satisfactory skill level and automated your performance, you have stopped improving.
• Once a person reaches that level of “acceptable” performance and automaticity, the additional years of “practice” don’t lead to improvement.

• Naive practice means doing something repeatedly, and expecting that the repetition alone will improve one’s performance. This is how most people “practice” but it’s ineffective.
• Purposeful practice has well-defined, specific goals. Without such a goal, there is no way to judge whether the practice session has been a success.

• Purposeful practice means having a plan - putting a bunch of baby steps together to hit a long term goal, 
• Purposeful practice is focused.
• Purposeful practice involves feedback: you have to know whether you are doing something right and if not, what mistakes you’re making.
• Purposeful practice requires getting out of one’s comfort zone, feeling uncomfortable. If you never push beyond your comfort zone you’ll never improve.
• It involves a way to monitor your progress and a system to maintain your motivation.

The reason that most people don’t possess extraordinary physical capabilities isn’t because they don’t have the capacity for them, but rather because they’re satisfied to live in the comfortable rut of homeostasis and never do the work that is required to get out of it.

The traditional approach to learning is not designed to challenge this: It assumes that learning is all about fulfilling your innate, fixed potential and that you can develop a particular skill or ability without getting too far out of your comfort zone. 

• They are mental structure that corresponds to an object, an idea, a collection of information, or anything else, concrete or abstract, that the brain is thinking about.
• They help with processing large amounts of information quickly, despite the limitations of short-term memory.
• Your skill in anything is based on the number and quality of “mental representations” you have for the skill.
• What sets expert performers apart from everyone else is the quality and quantity of their mental representations.

1. The field must be well developed. If there’s no competition to indicate skill, then it’s hard for there to be deliberate practice because the differences of the best are less clear.
2. It requires a teacher who can provide practice activities
3. Near maximal effort, constantly being taken out of your comfort zone by a teacher or coach. Not “fun”
4. Well defined, specific goals, not aimed at “overall improvement.”
5. Full attention and conscious action, no autopilot.
6. Feedback and constant little improvements, modifying efforts in response to feedback
7. Building and modifying mental representations

It offers the following view: anyone can improve, but it requires the right approach. If you are not improving, it’s not because you lack innate talent; it’s because you’re not practicing the right way.

Once you understand this, improvement becomes a matter of figuring out what the “right way” is.

Improvement is possible is we learn to let go of these myths:

1. The belief that one’s abilities are limited by one’s genetically prescribed characteristics.
2. If you do something for long enough, you’re bound to get better at it.
3. All it takes to improve is effort. If you just try hard enough, you’ll get better.

Keep in mind three Fs: Focus. Feedback. Fix it.

Break the skill down into components that you can do repeatedly and analyze effectively, determine your weaknesses, and figure out ways to address them.

• The best way to move past any plateau is to challenge your brain and body in a new way. Figure out the components of the skill that are holding you back, and find a way to push yourself more on those specific elements. Design a practice technique focused on improving that specific weakness.
• To keep working on something, you need to keep the reasons to continue high, and the reasons to quit low.
