"...Has anyone found a mental health facility that specializes in tax accountants? "

Rick, we do need to find one.  And it *better* serve good tequila !

Well said - our procedures are similar. 

I've worked alone for much of my career.  MY approach has always been to 1) determine the answer I expect.  Determine it a second time using a different method/approach.

See it the answers match.  

Rinse/repeat as necessary.
