Do you know which way to go?
Alice in wonderland:
“Would you tell me, please, which way I ought to go from here?” asked Alice
“That depends a good deal on where you want to get to,” said the Cat.
“I don’t much care where” said Alice.
“Then it doesn’t matter which way you go, said the Cat
“– so long as I get somewhere” Alice added as in explanation
“Oh, you’re sure to do that,” said the cat “if you only walk long enough”
So: if you wish to be one that choose the way, you should know where you want to get, first.
