Terada Masatsugu thinks that the value of reading is the product of three powers:
"author's power" × "your experience points" × "your business power."
You spend the time to read books. It is an investment. The efficiency of the investment is the value per time.
That says the value of reading is not determined only by the contents of books. To read much does not mean to get much value.
"Your experience points" is a metaphor of role-playing games. By collecting the experience points, the ability of the in-game character grows. For reading, there are three abilities:
"Your business capability" includes "ability to collect information from customers" and "ability to assemble models to understand customers' needs based on experience and information" and " Make and show it to customers and verify their understanding."
"Your business strength" is also a set of ability.
