It's important to understand that courage is not the absence of fear but rather how one reacts to fear. Now courage doesn't need to be demonstrated on a Herculean scale all the time. The simple of act of joining a gym if you are out of shape is a small act of courage. The point is that courage is something that manifests itself in our everyday life by helping us overcome our fears. We still feel the fear, but it is how we react to that fear that demonstrates to the world what kind of person we are.
Discouragement is much like fear in many ways.
In business, any endeavor is usually composed of many steps that are put together and lead to an ultimate goal. Building a company, for example, requires many steps. Along the way, there is a good chance that you would get discouraged. What you must keep in mind at all times, if you hope to become successful, is that discouragement is part of the game. That is, you will feel discouraged at times and that is when you must show the most courage.
