From the self affirmations of Stuart Smalley on Saturday Night Live, saying positive and nice things in front of a mirror helps a lot for decades. It helps us to concentrate. The practice in the video, the words and body movements help us to make more success and help us to achieve our goal.

David Sarwer is a psychologist at the Center for Weight and Eating Disorders at the University of Pennsylvania. He explains that, in fact, a mirror is one of the first and best tools he uses with some patients. He stands them in front of a mirror and guided them to use gentle and neutral language as they shape their bodies. “Instead of saying, ‘My abdomen is disgusting and grotesque,’ ” Sarwer explains, he’ll guide a patient to shout, ” ‘My abdomen is round, my abdomen is big; it’s bigger than I’d like it to be.’ ” The goal is to remove “negative” from the patient’s self-talk.

We all have an internal representation of our own bodies. Like reaching out a hand and picking up a coffee cup, we all need to think before take into actions and sometimes we say it aloud to remind us what we are suppose to do. Studies show that your internal sense is really powerful.

Research on what neurologists call motor imagery says that the neurological networks included both imagine movement and physical movement. Imagining a movement over and over can have the same effect on our brains as practicing it physically, and moreover we may do better on this physical movements.

In addition to a confident booster, your internal mind and physical movements will be largely reshaped. Psychologist Ethan Kross of the University of Michigan studied the pronouns people use when they talk to themselves silently, inside their minds. “What we find is that a subtle linguistic shift — shifting from ‘I’ to your own name — can have really powerful self-regulatory effects.” Sometimes you will have this experience. While walking down the street, your mind can’t stop thinking. Sometimes you talk to yourself with your own name instead of an “I”. Fun fact is, I did talk to myself with my own name. If I did well on a math quiz, I would say “You made it, Ran”. Although it is a subtle change, it greatly affects my mind and physical movements. For that rest of the day, I feel more confident and happy. And my friends who ate lunch with me, surprisingly, shared the same luck.

Self talk is Self affirmation. Talk to yourself more and think more will increase your possibility to succeed.
