ABOUT THIS VIDEO: If you are honest with yourself about who you are, meaning both merits and flaws, then no insults or criticisms can ever hurt you.
Because you will know what is false and be able to brush it off as that person's misinterpretation of you.
Conversely, you will know what is true and have the ability to say, "Yeah, well...I already knew that about myself, so what's your point?"
Nothing will take you off guard. Sometimes criticisms can do that, and they can hurt a lot when that happens. It's like when you walk through your house and bang your shin against a coffee table: it hurts even worse because you weren't expecting it.
Watch this video and learn how you can toughen up your "mental shins."
