In your life, you will be evaluated on your output. Your boss will evaluate you on your output. If you’re a writer like me, the audience will evaluate you on your output.

But your input is just as important. If you don’t have good input, you cannot maintain good output.

The problem is no one manages your input. The boss never cares about your input. The boss doesn’t care about what books you read. Your boss doesn’t ask you what newspapers you read. The boss doesn’t ask you what movies you saw or what TV shows or what ideas you consume.

But I know for a fact I could not do what I do if I was not zealous in managing high-quality inputs into my mind every day of my life. That’s why I spend maybe two hours a day writing. I’m a writer. I spend two hours a day writing, but I spend three to four hours a day reading and two to three hours a day listening to music.

People think that that’s creating a problem in my schedule, but in fact, I say, “No, no, this is the reason why I’m able to do this. Because I have constant good-quality input.” That is the only reason why I can maintain the output.

Your output depends on your input
