People will hate you, people will love you. How they feel about you and what they think about you need never ever affect you. They cannot cause you to feel anything, only YOU can. What YOU choose to think about what they think, say and do is what causes YOU to FEEL good or bad.
Stop using them, their words, action and thoughts as YOUR EXCUSE to feel this way or that way! Take YOUR POWER BACK by realising YOU are the only one in control of how you feel because YOU are the only thinker in your mind and what you CHOOSE TO THINK will affect not only how you feel but everything that happens to you. That is how powerful YOU are.
