Responsibility is a rare thing.

Pure, unqualified, unadulturated "I will take care of that" is one of the rarest commodities I know of.

Typically what you get is qualified responsibility.  "I'll take care of that IF blah blah blah" or "I'll take care of that AS LONG AS blah blah blah".  Maybe, possibly, I'll try, blah, blah, blah.

Nobody wants to hear that.  It leaves the matter up in the air.  It's weak.  It makes you look like a wimp.

On the flip side, you have to take the lumps when you screw up.  This is the part everybody is afraid of.  Look at the economic meltdown.  Plenty of people with blame here, yet I don't know of a single person who said "yeah, I messed up" except for Alan Greenspan.  Plenty of Senators helped bring you this mess, yet nobody mans up.  Cowards.  All of them.

Hearing "I'll take care of that, I will own it" is one of the most refreshing things I ever hear.  My respect for the person who says it instantly ramps.  Unfortunately hearing it is far too rare.
