"get out of the building"

"I wasn’t completely surprised because as a young marketeer, I made this mistake all the time – thinking that my product was a solution to someone’s problem  – without ever understanding what problems the customers really had. And that I needed to have all the answers when in fact I didn’t even understand the questions.

I suggested that perhaps he should get out of the building and actually talk to some large-scale concrete suppliers and rather than starting with what he wanted to sell them, try to understand what their needs were."
