Activities such as reading a lot of books, engaging in various physical activities and watching a lot of documentaries may or may not enlighten you.
Becoming super wealthy, becoming a person of high social status and making great achievements that are highly praised by people may or may not enlighten you.
Therefore, these aren’t the most efficient ways to become enlightened.
The best way to be enlightened is to suffer. Of course, nothing good would happen if you just let the pain make you suffer. As you try to escape the pain, you will start to try various therapies. You may start searching for spiritual solutions, scientific solutions, mathematical solutions, philosophical solutions, medical solutions et cetera.
At the end, you will realize that the only way to terminate the pain existed within yourself and nowhere else. It is at this moment that you would be truly enlightened.
