A young pupil in a quandary for direction, asked his teacher how he
may judge the battles upon which to draw his sword. "How, sensei,
should I pick my battles so that I may be victorious?"

The teacher paused, and with a firm wisdom, replied. "Young student,
this is not an easy question to answer, but I will give you the best
advice I can give you." He lowered his voice to a whisper.

"Beware the great beast, for he may slay you with a single
swipe of his claws or with but a blast of his fiery breath. Step
lightly and do not choose this battle with a thought of impunity."

The master lifted his eyes and raised his voice emphatically.

"Be mindful always of the rats that scurry about the beast’s legs, for they will surely devour you in time. Step boldly, and always take this battle wherever it can be found."

If you can do these things, you will be victorious and a champion in your own right.
