One must keep many options open at any given time.
But act on one at a time as if it is the only option.

Act like an arrow with each option.
Arrow can not hit two targets at a time.
Your mind and action are not in sync, you will miss the target.
Pitcher only sees the catcher’s glove.
Eagle eyes only one mouse on the ground.
So you too set aside the thoughts about all other options at that time.

Why to have more options then you may ask?

Dangers of failure also come to people of great skills.
Disappointment and despair needs option to refocus.
Dispersal when overwhelmed is principle strategy of guerrilla warfare.
Knowing when you move to next option is key to surival and success.

Keep many arrows with you but aim each one as if it is the last one you need to use.
