In the comment section below, please tell us the worst bit of business advice you've ever been given. Next Wednesday, I'll pick the top three and and we'll send out Dale Carnegie's book, Leadership Mastery, to the winners. (Special thanks to sister company Simon & Schuster for the prizes.)

Mum's the Word
If you communicate to people you manage all the difficulties the company is facing in tough times, it might demotivate staff, or they might pass on that confidential information to people outside the company --- and then where would you be? Best to keep it all confidential.
In my experience, the opposite is true. Keeping your people in the loop during tough times can actually motivate them to pull together and work harder.
OK, now it's your turn. Please add your nuggets of undavisable advice below.
