If you made a mistake, admit when you are wrong. Don’t beat yourself up. Be fair with yourself. Finding the right balance is something you need to continue working on.
Stop going over and over in your mind what you may have done wrong, and focus on what you've done right. Finding the right thoughts and words that support a sense of worthiness is so important for you.
Your doubts about yourself are merely thoughts, and those thoughts can change, if you choose to replace them. The transformation you need is in your words. So think before you speak. Be aware of how you act.
Choose positive phrases in everything you say, and you will see a change for the better. You can turn over a new leaf and shine so much brighter.
The secret is in loving yourself. The love you have for yourself makes all the difference. It is how much love you have within you and for yourself that determines how much you appreciate love.
