Sometimes it's okay not to know where you're going. Sometimes where you're going doesn't exist yet.

Whenever you have no blueprint to tell you what to do, you must act artfully....

...if you think you know where you're going, you're probably wrong....

Many people in business admit that parts of their work are "more art than science." What they often mean, alas, is that they don't understand those parts. "Art" used in a business context usually refers to something done by "talented" or "creative" people who are not quite trustworthy, who do work that resists reasonable description. There's often a disparaging implication that art-like processes are immature, that they have not yet evolved to incorporate the obviously superior methods of science. The premise that underlies this point of view equates progress with the development of reliable, rules-based procedures to replace flaky, unreliable, art-based processes. We reject this premise.

The quotes above are from an article at HBS Working Knowledge about why managing innovation is like theater. Theater and other collaborative art projects may make better models for knowledge work, the authors say, than more traditional rules-based, scientific processes. Cheap and rapid iteration, gaining experience rather than spending time on detailed planning can lead to faster, better results.
