Here is a great post on this topic by Tom Evslin where he provides a 10 point list to do a self-assessment to determine your entrepreneur quotient (for lack of a better phrase)

11. Chris Yeh adds one more item to the list called Reality Distortion Field.

I have a few to add but here is one that I like most.
12. You won’t let uncertainty slow you down.

I wrote about this a few days ago in the Distinguish yourself series.

Have fun!
