"If you want to master something, teach it." - Richard Feynman
More specifically:
- Pretend to teach a concept you want to learn about to a student in the sixth grade.
- Identify gaps in your explanation. Go back to the source material to better understand it.
- Organize and simplify.
- Transmit (optional).

This could be simplified in this way: If you want to make sure you understand something, give a Powerpoint presentation about it to a group of 12-year-olds.
