A man hunting tigers in India was suddenly surprised by a huge Bengal tiger - it was almost on top of him. The man raised his rifle and fired, but he overshot and missed. The tiger, frightened by the man and thrown off stride by the noise of the gun, leaped toward the hunter. But the leap was to wide, and he missed his prey.
The man returned to camp and spent several hours perfecting his aim for short distances and quick firing. On the following day, he again stalked the tiger. Finally, he spotted the beast at some distance. The tiger was practicing his short leaps.
Management lesson: Don' t think too soon you are ahead of your enemy/competitor.
