My motto is that everything is in your head. If your mind believes you can do it, your body will follow. So what do you do when mind refuses to believe?
The relationship between the mind and the body goes both ways when the body does something, the mind believes it.
You can test it out, when you are feeling down next time smile and continue smiling. Make it a huge grin, from ear to ear, let your eyes smile as well. Your mind will recognize the happiness on your face because it has made your face do that same expression many times. You will essentially trick your mind and it will believe you are happy, at that moment mind will send signals to your body and the body will believe it is happy as well. And when both the mind and the body believe, clouds will clear and you will be truly happy. 🌞
