From the Magic of Space, some thoughts about fear, ignorance, and how much power we have to overcome these fairly easily. From Chapter VII, The Self - Its Relation to Space and Matter:
First, you should realize that all uncontrolled emotions are the result of ignorance or undevelopment, and this knowledge will rob them of their power over you. You will know that you are at the emotional point in your evolution, which is an indication of ignorance of your own power of self-control. Then you will begin to see the need of development, and will set about correcting the fault. A child fears the dark because he does not know its nature of its cause. If he is carried into a dark room and the light is turned on, and he sees nothing there to injure him, his fear is immediately dissipated. His fear was banished when his ignorance was destroyed.
If you can show a person that there is no "bad luck" except that which he has created, and that the "evil" he fears he builds for himself, immediately you destroy the power he has given to these conceptions. If a man is vain of his knowledge, and he can be made to see that the field of knowledge is unlimited, and that his vanity over the small amount that he possesses is but an indication of his great ignorance, immediately his vanity disappears. So it is by enlightenment that any or all of our emotions are controlled or eliminated from us.
The second great aid is this: if we understand what habit is, and know the law which underlies it, and if we know that much of our yielding to our lower natures and lack of self-control is a matter of habit, we shall be able to destroy habits much sooner than if we do not understand them. There are two elements which enter into the formation of a habit. The first is what might be called the law of periodicity, or periodical return, and the second is the initial impulse. The law of periodicity causes a thought or an act to be repeated within a determinate time. The intensity with which the thought was projected, or the act performed, determines the time in which the tendency to repeat itself will manifest.
