It is a fact that tomorrow's practice is today's thought. What begins today in our conception expresses sometime later in our actions. Today we possess subconsciously the knowledge required for unfailing success. If we can discover and make conscious that knowledge, we can acquire perfect mastery now. It is also true that what expresses outwardly is an expression of an inner potential.
External mastery is an expression of an inner human potential for unfailing success.
Go inside, discover the potential, rather than waiting years for it to emerge. Bring it forth consciously and you will see the truth of the above statement. When the subconscious knowledge is made conscious, or the inner potential is brought out as an outer actuality, the element of failure recedes and finally disappears. Take, for example, the act of negotiating to buy or sell something. Next time, instead of becoming engrossed in bargaining, go inside yourself, examine the earlier negotiations that failed and identify the reasons for failure.
