Let's start with this reality: people aren't paying nearly as much attention to you as you think. I promise you, they aren't.
They have their own lives, their own problems, their own dreams... They don't go home, sit on the couch and think about you.
So we need to stop giving other people's opinions and feelings so much weight in our lives. They say one negative thing to us - and we change our entire lives based on that comment. Meanwhile, they forget that they even said it.
Instead of giving other people the power in your life - hold it for yourself! And start using it today.
