Are you an Expert ?

I am not an expert in any field. I am very learned in several. I always know enough of a field to be dangerous. I have never tried to be an expert at anything. I get bored after awhile and learn a new field. I would rather know something about everything than to know everything about one thing.

i think iam not expert in any field. but i play well the chess game. but iam not expert. i want to become expert in logic thinking.

I may think whatever I want, But my dear friend, does it have any meaning? You grading or examining yourselves? I think you should be certified by the senior and experts in that respective field, in which you claim your expertise. Unless admired by others and recognised by the people, you can't be correct neither you yourself can't say that.
