Courage is a major ingredient for success. It is very easy not to be successful as misery loves company, and success breeds contempt.
If you do not want to make waves, stay ordinary or mediocre. By doing the things that every other person does, going where they go, and acting like them, you will neutralize your God-given abilities.
You need courage to be different, to stand out, and decide to chart a different course from other people. It takes courage to get out of your comfort zone; it takes courage to get out of the box; it takes courage to be successful.
