Who's the fastest?

Two crows were flying home after a long day when suddenly a rocket whizzed past them. One crow asked, "What kind of a bird was that? It is able to fly at such pace in spite of flying throughout out the day." The second crow replied, "I don't care what bird it is but I would fly at the same speed too if I had my tail on FIRE."

Similarly, many of us wonder how some people are able to succeed in spite of all their difficulties. Well! They have FIRE within them.
