Belief

You will admit that it is your behaviors and actions that create your life, you will admit that it is your behaviors and actions that create the results. So when you believe that you can achieve a goal, you subconsciously believe it, you will behave and act differently from that you don't believe you can achieve your goal or differently from you are neutral(You don't know if you will achieve your goal). Your behaviors and actions will be guided by the belief that you will achieve your goal. It's like that you drive a car. There are many roads which lead to different destinations, and since you believe that you will achieve your goal, you choose to drive the road which will lead to the destination of achieving your goal. Whenever there is a fork, you always choose the branch which will lead to the destination of achieving your goal, therefore you will certainly achieve your goal.

Just see if you believe you can achieve a goal, and you subconsciously believe it, see if you will behave or act differently. Since your life is created by our behaviors and actions, different life is created by different behaviors and different actions.

So based on the fact that you believe you will achieve your goal, what will your conscious mind(your rational mind) do?

I will try to make it happen, I will try to think how to make it happen.

So if you don’t know if you will achieve it, what will your rational mind(conscious mind) do?

I will not wholeheartedly think how to make it, I will not wholeheartedly try to make  it happen.

So what will you do?

I will think what I will do if I don’t achieve it.

In this way, do you think that it can happen?

No.

Why?

Because I don’t try it wholeheartedly.

So what if you don’t believe if you will achieve it? What will you do?

I will quit.

Why?

I don’t want to waste my energy and my time.

So will your goal be achieved if you quit.

Of course not.
