Good thinking doesn’t happen by passive osmosis of other people’s good thinking. You have to actually write essays and journals to debug yourself and your ideas. And then, crucially, act (a) on this thinking.

Consider a university professor teaching a course. Does she say anything original? Do you think she should cancel her course because somebody else discovered the things she wants to teach? Or does she have to cancel her course simply because there is a similar course at some other university? Or consider yourself. Do you avoid having conversations with your friends when you think you have nothing original to say? Do you share things with them? Do you give advice? Do you help to understand things?
