Success is all very relative wouldn't you say? Yes, I think that someone is Calcutta who happens to have good running water, food to eat every day and good health would consider themselves successful. However here in the west we see success so very differently.
Our desire to manifest success is driven by a need to have many things. We are always in a state of wanting. We want more money, we want more cars, we want... This state of wanting keeps us at a vibration of being without. We cannot manifest what we don't already feel deep inside of our being. The law of attraction can only give to you more of what you already have inside.
When you being to see how successful you are in the small ways you can begin the training of the mind to see, think and feel success. As you feel yourself already successful and abundant your send out those frequencies then attract all the conditions which match those mental frequencies.
Train the Mind
By training your mind to see success in your life as well as success in others you will begin to manifest success in your own life. You manifest what you observer in your environment. So if you do not feel particularly successful you can begin to observe successful people and the more you do the more you send those signals to your mind. As your mind is feed those images of success it begins to assimilate those ideas into your being. Bit by bit you begin to change. Soon enough your ability to manifest the successful life will be rapid.
There are many techniques and principles often unknown to many people that can increase your manifesting ability to outstanding levels. The idea is to learn and train yourself with those techniques until you see powerful changes.
