If you see things going wrong, you must act.
You can’t simply put it in writing or voice your concerns.
Covering your arse might be useful in corporate politics, but in the real world it’s meaningless.
In the real world, being right is irrelevant. The only thing that matters is success.
Success means action, not words.
Written letters are useless.
Make the change happen, get your ship back on course.
It’s not good saying “I told you so.”
