Me: Instead of doing X we could do Y, that would be better.
Boss: No, bad idea we keep doing X.
a few months later
Someone external: You could do Y
Boss: That is a great idea. lets do Y.

Why does this sound soo familiar...

I‘m glad about the fact that people can‘t hear my thoughts in such situations.
I‘d be in jail in no time.

I cannot tell you the amount of times I've got changes through, a few company wide, and every time it was by first identifying who makes decisions, and second determining who they will listen to.

And when I tell people that want something done but cant get it, that I can get it done, its always "that's impossible. They already said no."

Well, they said no to *you*.
