Belief produces emotions.  Emotions produce thoughts.  Thoughts produce Actions.  Actions produce Results .... author unknown.

Think about where you are in your life.  Where you are is the result of your actions.  Go backwards to think through how you got where you are.  Can you see this?

What actions got you here?

What thoughts produced those actions?

What emotions produced those thoughts?

What belief produced the vision?

You can change your actions for a while without changing anything else, but sooner or later you will cycle back and ulimately repeat your performance.  You may have already tried this. (If you keep doing what you've been doing, you'll keep getting what you've been getting.  It's insane to keep doing the same things over while expecting different results.)

If you want to change your actions permanently, you must change your belief system.  What you believe is the driver.

Do you have confidence?  Confidence means "with faith".   In whom is your confidence placed? 

Here is what God says - For I know the plans I have for you,” declares the LORD, “plans to prosper you and not to harm you, plans to give you hope and a future. - Jeremiah 29:11. 

It's your move.
