The cheshire cat has it right in Alice in Wonderland:
"Would you tell me, please, which way I ought to go from here?"
"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 an explanation.
"Oh, you're sure to do that," said the Cat, "if you only walk long enough."
You're bound to get somewhere eventually if you are moving. But with no aim and especially with no direction, you'll end up anywhere, or worse never realize that you actually got somewhere. With direction and focus, you'll get to where you want to go, and much quicker as well.
