In order to learn you must learn the process of learning itself. This may seem trivial, but this can be a barrier for picking up new skills, adapting to changing technologies, and making habitual changes. It is also useful for understanding how to do this efficiently.
The trivium method is a simple framework for learning that can be explained as follows:
Input: Take in high quality information. Spending the appropriate amount of time on this step is critical to learning quickly. Traditional education formats tend to have excessive focus on this step.
Process: Processing the information obtained from the previous step. This step is required to obtain true understand. Blind acceptance of facts without thinking for oneself will not lead to understanding.
Output: Put the information into use, take action. This can take the form of teaching or practicing a skill. Efficient learning requires repeating this step often.
To truly learn well requires repeating all three steps. To learn quickly we need to emphasize putting processed information into action as soon as possible. Getting stuck on taking in information will not lead to practical applied knowledge. Getting stuck on processing leads to indecision and inaction. Jumping to action without information and processing leads to misled action out of ignorance.
It is only when we use information to act logically that we learn practical wisdom. It is only when we repeatedly apply practical wisdom that we grow wise.
