Positive thinking

I have just read a book about positive thinking which i find that this habit is of utmost important in everything we do in our life.
I believe that we are what we think, so let our thought to be all positive, encouraging and drive us to achieve what we desire. Positive thinking lead us to peace of mind and increase our self confident, thus, we have a feeling that we are competent in any endeavor that we undertake. Try to mix around with all your friends which have the same mindset, negative thought is to be eliminated from the mind.
