It is not about being an engineer, or a manager, or a marketer, or whatever your job description is.
You really have only one job, to relieve someone else's pain.
They are trying to do something, and they cannot do it themselves, that is pain. Your job is to make that pain go away. You don't even have to do it yourself, you can just get them together with someone you know who can make their pain go away.
That is the essence of entrepreneurship.
