Do you feel like you are someone who just isn’t courageous? If so, you are only lying to yourself. Courage is not a natural trait. It is all about being afraid to do something, but doing it anyway. It is something everyone is capable of having, if you are willing to accept the potential consequences of what could happen.
Moral Letters 13.6-7 states Do me the favour, when men surround you and try to talk you into believing that you are unhappy, to consider not what you hear but what you yourself feel, and to take counsel with your feelings and question yourself independently, because you know your own affairs better than anyone else does. Ask: "Is there any reason why these persons should condole with me? Why should they be worried or even fear some infection from me, as if troubles could be transmitted? Is there any evil involved, or is it a matter merely of ill report, rather than an evil?" Put the question voluntarily to yourself: "Am I tormented without sufficient reason, am I morose, and do I convert what is not an evil into what is an evil?". You may retort with the question: "How am I to know whether my sufferings are real or imaginary?" Here is the rule for such matters: We are tormented either by things present, or by things to come, or by both. As to things present, the decision is easy. Suppose that your person enjoys freedom and health, and that you do not suffer from any external injury. As to what may happen to it in the future, we shall see later on. To-day there is nothing wrong with it.
