Let us analyze the part that mental attitude plays in our lives and we shall learn how important it is.
Your mental attitude is the major factor which attracts people to you in a spirit of friendliness, or repels them, according to whether your attitude is positive or negative; and you are the only person that can determine which it shall be.
Mental attitude is a determining factor- perhaps the most improtant factor- as to what results one gets from prayer. It has long been known that when one goes to prayer in a mental attitude swayed by fear, doubt, and anxiety, only negative results are experienced. Only the prayers that are backed by a mental attitude of profound FAITH can be expected to bring positive results.
Your mental attitude determines, to a larger extent, whether you find peace of mind or go through life in a state of frustration and misery.
Mental attitude controls, very largely, the space one occupies in life, the success one achieves, the friends one makes, and the contributions one makes to posterity. It would be no great overstatement of the truth if we said that mental attitude is EVERYTHING!
