Having Positive Thinking Will Open New Doors To You

I read an article written by Lizzy Bronte (http://lizzybronte.net/the-power-of-positive-thinking/) regarding the power of positive thinking. I quote:

"Have you ever paid attention to what you’re thinking? I mean really notice what thoughts are racing through your head?  Do you realize that your thoughts can define the direction you take in life?Let’s say, you have thousands of thoughts everyday and most of those thoughts are either negative, useless and really don’t help you get what you want. "

It's pretty normal that a lot of things can enter our mind whenever we do our day to day chores especially when we are commuting or if we're alone in our room. I mean if we really get into the idea of being negative then it will manifest on the outside. We have the control of our own emotions. If other people are involved, let go of how pissed you are to them. Remember, you have total control of how you react to that person or that certain situation - control your reaction. 

Any thoughts?
