Do you hear yourself?
What are you saying? Would you talk to other people that way?
If you look in the mirror and give yourself a ration of sh!t, it's time to rethink the way you talk. You wouldn't walk up to me and point out my oily skin and the extra fluff around my middle, would you? Of course not.
Try talking to yourself in the same uplifting, encouraging way you would talk to your best friend. Stop the tape of negative comments that has been on an endless loop since you hit puberty (or before). Do you even need to hear any of that? Of course not!
