Why are so many stuck in their old beliefs?

An old Zen story tells that you must empty your cup before you can achieve something new. This applies also to your life situation.
You must dare to give away in order to make room for something else to replace it.
If you have a garage filled with old car tires, an old furniture, or stuff you did not use for a long time then give it away.
Alternatively, do you have old cloths you never are using, give it away.
Do not sell it and receive money for it, because when you give, you shall receive. This is the law of reciprocity in action. The same is the case with your wants. You must make room for the good you would like to receive. Most people are not aware of this law. They spent most of their life with not taking any action and not really deciding on what they want. This is very confusing for them and they are not clear in their mind, but are instead lacking of visions and expectations. Consequently, they are not achieving outstanding things in their life in spite of the fact that they have the same opportunities as all other people.
How to look at yourself as a vibrating energy?
Most people are stuck because of their fear, uncertainty, and insecurity. This is a negative self-perception and a lack of confidence in them, to life and other people. It is a vibrating energy field within people affecting their life to attract similar vibrating energies.
They cling firmly to what they have and will not let go the old thing or beliefs.
We cannot own anything and therefore it is paradoxical that so many stick to old things, old beliefs, old habits and old ideas.
You have created anything that is of imperfections in your life. The universe creates only perfection.
You must make room for the power of the infinitive universe can flow freely through you if you want to achieve something new in life.
You should see your body and mind as a vibration that receives energy and that the universe is in resonance with you and is free of obstructions of any kind, whether physical, mental, psychological or spiritual obstacles.
Your assets in your life are like the leaves in a flower.
They must all be present to form a whole flower.
However, the heart of all the leaves is your essence. The field of infinite intelligence and power, which the mind cannot comprehend, but which is the root cause of all causes.
All your assets are present in the flowers leaves coming out from the center of the flower. Allow your personal development to grow and empty your cup from time to time.
Finally, your mind is crucial for your joy of life and for your wealth in your life and not only wealth in the meaning of money. If you have less happiness in your life, you will have less joy.
