In other words…forgive yourself and hug yourself…this is a new day. The past is the past. It is a different country, they do things differently there. You have most likely punished yourself enough, learnt your lessons and now you can do things…differently. React to things differently. Have a new life.
If your negative inner dialogue is especially persistent, try to turn it around. Write down all your negative thoughts and turn them around, into positive affirmative statements:
E.g. I am not good enough artist. turns into I am working towards becoming a brilliant artist. or even I am a brilliant artist. Whichever one sounds/rings more true to you.
You could even try to say these to yourself in front of a mirror. It might feel quite a bit unnatural at first…but soon enough…say in three weeks of reaffirming…it is likely to become your second nature, new belief system, supporting your new set of actions.
Go, experiment, report how it went.
