Myers-Briggs is an incredibly accurate test (atleast for me). My company paid for a Myers-Briggs company to actually bring their people here and do the full test (8 hours) - I'm an ENTP. :)
Very close to an ENTJ, except I don't write anything down or have any organization! I will make a 'to do' list, but not follow it!
The test everyone is posting about here is accurate, and a LOT cheaper than what we had to pay!!
