How you think, in combination with your actions, determines your results in every area of life.
Your biggest breakthrough will come as you learn to think differently. Albert Einstein said, "We can't solve problems by using the same kind of thinking we used when we created them."
If you want to breakthrough to the next level in any area, then you will need to shift your thinking to do so. As an example, it's impossible to double your income thinking the way you currently do. The reason is because your actions are an outgrowth of your thinking.
So unless you learn to think differently, nothing will change with respect to your actions.
Start with your thinking. Change your thinking and you change your world!
