If my knowledge of myself is incomplete, can I know myself better through other people?

Where your eyes don’t go a part of you is hovering. It’s a nightmare that you’ll never be discovering.

The short answer to your question is yes. I’m not familiar with the person in that image.

you can at least know how you seem to others, but i recommend taking a large sampling for best representation of data mean and breadth

That would be tricky data to collect. I'm picturing those ghastly "what do you guys think about me on this stream" type memes. Whatever my current disposition towards someone, reading thirsty polls like that has a negative influence in it. It's like, why can't they just pretend they don't care what anyone else thinks about them like me? 😝

Might have said the quiet part out loud there...

lots of people care what other people think, but they wouldn't be very good independent thinkers
