Yes, a strategy. Without it business will say 不靠谱 (boo cow poo, 
aka unreliable) and flee.  You never wanna hear that from 
customers, and when you do, bust your ass to build trust that was 
lost.

If you don't know where you are going, and road will get you 
there.

(lyrics) But she wants everything
(He can pretend to give her everything)
Or there's nothing she wants
(She don't want to sort it out)
He's crazy for this girl
(But she don't know what she's looking for)
If she knew what she wants
He'd be giving it to her
Giving it to her
I'd say her values are corrupted
But she's open to change
Then one day she's satisfied
And the next I'll find her crying
And it's nothing she can explain  ------

If She Knew What She Wants
