When we do what everyone else does, we’re following conventional wisdom. Conventional wisdom is a double-edged sword. For instance, conventional wisdom tells us that we shouldn’t steal. This principle works in humanity’s favor. But sometimes laws are unlawful. Slavery, for example. It was legal, but insane!
This is the type of outcome we can end up with when we don’t think for ourselves. When we don’t question the status quo. When we’re focused on fitting in.
Thinking for yourself doesn’t mean never listening to others. It means holding those ideas in your mind without losing sight of your own ideas. It means learning from others, but not merely parroting them. It means listening, but not automatically accepting.
