Once they’re made, see where you could have done things differently and then thank the Universe for pointing you in the right direction. Make a note of it and then let it go. Say bye- bye to it. Don;t let it stay in your head taking up space in there because it doesn’t belong there anymore. So scoot it out. Fill your thoughts with positive ways to make things better.
Mistakes serve a valuable purpose- they show you how not to do things. But past that- they just need to go.
