A major turning point in your thinking comes when you change your language from “whether” to “how”. When you start thinking about how you are going to accomplish something you want, and you simultaneously refuse to consider whether it’s possible or not, your entire mentality begins to change. You do get what you think about most of the time, and if you continually think in terms of how you can achieve it, and the specific actions you can take to remove toward it, you are much more likely to be successful in the end.
As Shakespeare wrote, “There is nothing either good or bad, but thinking makes it so.” You live in a mental world. Nothing around you has any meaning except the meaning you give it with your thoughts. If you can change your ways of thinking, you change your life.
