I came across this today and wanted to share:

• A boss creates fear; a leader creates confidence.
• A boss creates resentment; a leader breeds enthusiasm.
• A boss says, "I"; a leader says, "We".
• A boss fixes blame; a leader fixes mistakes.
• A boss knows how; a leader shows how.
• A boss makes work drudgery; a leader makes work interesting.
• A boss relies on authority; a leader relies on cooperation.
• A boss drives; a leader leads.

And I’ll add one more to the list:

A boss parades his power before others, but a true leader uses his influence as opportunity to empower others to be powerful, too.

I think Mark Twain says it better:

“Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.”
