"The smallest of interactions with your employees can have an enormous influence on how they perceive you as a leader -- and help you reach your business's goals." - so says Roger Pearman on Inc.com.
This is along the same line as my earlier post about paying attention to subtleties. As leaders, we all need to remember that our every action is scrutinized by the people around us. We can't afford to let our guards down. You may never recover from a careless mistake in some people's eyes.
