> if you've done great work, if you've produced superb software or fixed a fault with an aeroplane or investigated a problem ... without telling anyone, your work is wasted
Completely disagree though. That work hasn't been wasted if that software is used, if that aeorplane can fly safely as a result.
Knowing how to advertise oneself can be useful but some people can also take pride and sense of accomplishment in doing things silently and knowing they did something useful.
And there's a difference between communicating, and advertising. There's an overlap, but it's not the same thing. Communicating is crucial. Advertising... not as much and wildly dependent on the situation (like trying to land a job).
