… asked someone what he did for a living and got a 10-minute answer.

It may seem that giving lots of detail is the key to an explanation. In most cases, it’s the exact opposite.
If you have any hope of my understanding what you do – let alone remembering it two weeks from now – you need to hyper-simplify it.

Your job is to tell them what the box is!
