I distinguish courage from confidence by the latter requiring evidence. You require evidence that your actions will be successful if you want to feel confident. But courage needs no evidence; hence, its bold audacity.
I’ve gained a defiantly unshakeable confidence over years of observing the results of my behavior: when I take risks for a cause with an intention which exceeds my own private benefit, then my actions result by generating not only the abundance necessary to achieve the objective of the cause, but true surplus compensating the impact and efforts of the original risks taken.
However, before that confidence was the need for courage to take the risks without having the evidence that my audacity would prove successful… like jumping off a cliff into a cloud bank, uncertain of the concealed surface within.
When is the last time that you did something for the first time? Will you take a great risk in something you truly believe to be of significant value for others?
Leap and you will be caught.
