Introspection is key. Are you actually nice or do you just think you are?

Would an average person describe you as nice? I’m not saying you should care what others think, I’m saying you can use what others say as a starting point, especially if it’s someone whose opinion you respect.

I don’t care if racists or sexists call me intolerant, but you can be sure that if my best friend who is a very sweet person said I’m being hateful then I would take that to heart and reevaluate my biases and preconceptions.
