I think one is better off not knowing their IQ. I don't think having a high iq is meaningless; in general it is helpful. But I find skills and abilities to be very "spiky". I am proficient in a narrow analytic area, and yes, it helps me make an excellent living. But my skills beyond that area are either mediocre or poor. In particular, I have very little mechanical ability and almost no practical skills. OK, I pay people to do these things for me but such is the peril of walking around thinking you are smart. My brother, a former D 1 All American and Econ Phd is very bright and over the top wealthy as his spiky skills apply to money management and investment - with an unparalleled 30 year record. Yet his practical skills too, are limited, and again, it is risky to walk around thinking you are smart. In any event, you are only as intelligent as the last thing you did, and in hindsight, some moves turn out to be rather dull. Do what interests you - work is a lifelong thing and doing something you do not like is very difficult and can take years off your life.
