From the book - As a man thinketh by James Allen

As a man thinketh in his heart so is he. A man is literally what he thinks, because his character becomes the complete sum of all his thoughts. As the plant springs from, and can not be without the seed, so does every act of  a man springs from the hidden seeds of thoughts and can not have appeared without them. Act is the blossom of thought and joy and suffering are its fruits.
-James Allen

I agree with everything said by this author. What ever we give our strength, thoughts and time - we become. There is no two ways about it. When all you can say or think are negative - my dear, you are headed towards self- destruction. You can only attract what you give you time, energy and thoughts to. Next time, when you catch yourself tolling that negative path, stop, breath and redirect your path. Only you have the powers to change things,It is not magic, it is not transmitted or transferred. Change for you, then you can change the world.

Stay focused.... Stay positive.
