Thats a heck of a statement to hear isn't it!
Allow me to clarify, YOU are not that important in someone else's life. See when we worry constantly about what other people think, it means we think they must be thinking about us A LOT - but the truth is they are not!
Not because they don't care, but because they are the centre of their own world, not you. And, they don't criticise you like YOU criticise you.
Feeling 'not good enough' is the underlaying cause of low self worth, anxiety, depression and staying stuck in a rut. Once you realise you don't have to MORE than you are, just be ALL that you are, it is easier to let go of caring so much about what other people think of you......Listen to the end for probably the most important short sentence of the whole episode.
