Here is what it has to say about this site / me (?) ;-)
ENTP – The Visionaries
The charming and trend savvy type. They are especially attuned to the big picture and anticipate trends. They often have sophisticated language skills and come across as witty and social. At the end of the day, however, they are pragmatic decision makers and have a good analytical abilitity.
They enjoy work that lets them use their cleverness, great communication skills and knack for new exciting ventures. They have to look out not to become quitters, since they easily get bored when the creative exciting start-up phase is over.
Well, just saying, if you ask others who I had/have worked with, mileage will vary ;-)
