The Law of Success is one that applies to anyone who wishes to use it. It is a state of mind and course of action through which you can attain anything you wish.
One of the ideas is that anything is possible, so get those negative self defeating thoughts out of your mind. Only think positively and with purpose. Do not accept no for an answer, in other words do not quit. It took Thomas Edison over 10,000 tries to create the light bulb. When asked why he kept on after so many failures he stated that "Those were 10,000 learning experiences, not failures. They are only failures if you let them be and do not learn anything from them."
