I am...

"I am calm"

Just for today, choose to say, "I am..." and finish the sentence with a word that describes you at your best, or how you want to be.
So, make a shift from:
I am late
I am fat
I am lazy
I am swamped
I am stupid
Try, "I am strong." or "I am LoVe!"  Choose something that resonates within you.
Today, I chose "I am strong" while doing pushups at the gym.  Let me tell you, choosing "I am strong" over "I can't do this!!" made a huge difference.  Try it!
