What you think eventually happens after sometime. It is kinda linked to the power of the mind. Ever watched the video THE SECRET?It is all manifested there. How the mind works on something we always think like, ever wonder when you are caught in a traffic jam and your mood becomes bad the whole day and eventually you end up not appreciating everything that happened?Well it is because when you got frustrated with the traffic jam you channeled your thoughts into expecting more irritating situations.What we think might not happen in an instant but eventually when we always think about it, it happens.
