Love this point you make in particular:  "As a leader, your desire to help others be successful should result in you making your expectations clear."

You also point out the importance of choosing to be trustworthy.  A leaders role is often to bring people to choice - setting clear expectations is one way to do that.  When you set clear expectations you remove the "wriggle room" someone has to justify why they didn't deliver and instead cause them to choose so they can be personally responsible for the consequences of their choice for better or for worse.

Thanks for adding your wisdom Deb!
