All those great things that you want to do, be, and achieve. Write them like they have already happened. Believe it or not, it will start to sink into your subconscious until you find yourself making these things happen. This is permission to be a little insane. In fact, this exercise might make you feel a little funny at first, but if you keep at it, in time you won't even be able to find your inner critic.
Nothing makes it shrink like a face to face showdown.
So gather your courage, and look in the mirror. Instead of criticizing yourself, as we so often do, give yourself some encouragement. Biblically we are told to treat our neighbors like ourselves. Unless, we start treating ourselves better. And it is high time we did.
