If I could say it better than Kathy Sierra, I would, but I can’t. (If I could draw cool pictures like Kathy, I would, too.)
If all managers like you, are you safer than if some think you’re amazing while others think you’re the poster child for Bad Hiring Decisions?
No one is safe. We’re all expendable. So why not try something risk and be outstanding, rather than mediocre?
In that vein, please read The Zone of Expendability?
And if your manager catches you doing it. Just smile.
