the grinning cat

"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 Cheshire 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."

---Lewis Carrol, Alice's Adventures in Wonderland

You'd be surprised by how far you could go if you only walk long enough.

But you've better know your target, or you're sure to regret.
