Equations are a great way of looking at life. They reduce things down to mathematics which then lends itself to other calculations you can do on the equation.
For the equation which is the focus of this post, if your reality is not what you want, you have two choices. You can either become more focused on your goals and the execution of your goals or you can reduce your doubts. Either of these actions is going to increase your reality.
If your doubts are big, that is the place to start because they will have the biggest effect on the equation. If your goals are small, focusing on them will have the biggest effect. Either way, seeing them as two terms in an equation allows you to play with the math.
How many other equations do you have for your life?
