Attitude.  To the prior poster: I went to UPT as an MEII with ATP mins met.  And I crushed it.  What always bugged me though, were the IPs that can't wait to slip the above gem into a conversation.   
To be fair, yeah, even I had a fair amount to shake loose in terms of "regardless of what you know, the AF wants it done X way".  But at the end of the day: attitude.  #1.
