What would happen if you speak more affectionately to yourself?

You must be aware of one thing: Your internal dialogue can directly affect your health, both physical and psychological. That limiting self-talk impairs your self-esteem and shuts down your potential, resources, and opportunities. Thus, you must change its docus. 

A simple way to achieve this is by addressing yourself in the second person instead of in the first person. This is a way to assume the role of a friend, who wishes the best for your and is attentive to correct your internal dialogue.
