The other day I found this interesting note on the internet:
In the time of the great explorers Columbus, Magellan, and Drake many areas of the earth’s surface, especially the oceans, were uncharted. Most of the people still believed that the earth was flat. Legend among seaman held that sea monsters and other creatures lived in these uncharted regions. As a result, the map makers of this era commonly place the words “beyond this point there be dragons” on uncharted areas.
That is the way we feel when we get outside our personal comfort zones, beyond this point there will be dragons. But if we want to grow outside our current comfort zone then we have to challenge these dragons now and then.
