There are four simple steps to the Feynman Technique, which I'll explain below:
Choose a Concept
Teach it to a Toddler
Identify Gaps and Go Back to The Source Material
Review and Simplify (optional)
If you're not learning you're standing still. So what's the best way to learn new subjects and identify gaps in our existing knowledge?
Two Types of Knowledge
There are two types of knowledge and most of us focus on the wrong one. The first type of knowledge focuses on knowing the name of something. The second focuses on knowing something. These are not the same thing. The famous Nobel winning physicist Richard Feynman understood the difference between knowing something and knowing the name of something and it's one of the most important reasons for his success. In fact, he created a formula for learning that ensured he understood something better than everyone else.
It's called the Feynman Technique and it will help you learn anything faster and with greater understanding. Best of all, it's incredibly easy to implement.
"The person who says he knows what he thinks but cannot express it usually does not know what he thinks."
— Mortimer Adler

Step 1: Teach it to a child
Take out a blank sheet of paper and write the subject you want to learn at the top. Write out what you know about the subject as if you were teaching it to a child. Not your smart adult friend but rather an 8-year-old who has just enough vocabulary and attention span to understand basic concepts and relationships.
A lot of people tend to use complicated vocabulary and jargon to mask when they don't understand something. The problem is we only fool ourselves because we don't know that we don't understand. In addition, using jargon conceals our misunderstanding from those around us.
When you write out an idea from start to finish in simple language that a child can understand (tip: use only the most common words), you force yourself to understand the concept at a deeper level and simplify relationships and connections between ideas. If you struggle, you have a clear understanding of where you have some gaps. That tension is good –it heralds an opportunity to learn.
