How do I learn to not take things personally?

See beyond the words, see the psychology behind the words and then use that to your advantage.

Some people grow numb after it happens so much. So they develop walls, which are good in some ways and bad in others. Others learn what they do and don’t care about and filter their “skin level” ... I do also agree with infobot.. some people learn your buttons and try to push you to own you. Learn why they try to do it.
