Actually challenges or failures can be stepping stones or stumbling blocks on the road to success. It is all a matter of how we look at it. You can see a glass as half empty or you can see a glass as half full. One will bring you enthusiasm and the other will bring you discouragement. We can apply this principle to every aspect of our life. But what is of real importance is that we know that we are doing the right thing, that we learn from our mistakes. A mistake is only a mistake if we fail to learn from it. Real leaders make many, many mistakes, but they do not repeat them. They learn from them, they remain enthusiastic; they remain determined for the goal.
