“Thinking outside the box” has become a common phrase, especially in business. Smart people realize: that usually means leaving the boxy building they’re sitting in.
Thinking outside the box, however, is extremely difficult when you don’t know what box you’re thinking in. Which unstated assumptions govern your thinking? What don’t you know about the limitations of your imagination?
Figure out what box you’re thinking in. Probe the boundaries that define your thoughts. Only then will you be able to think outside of them.
