Rather than have intelligence [not that its not an disadvantage to be a bright spark] I think common sense is more useful.I knew managers of companies who were very intelligent but some lacked common sense.As far as integrity goes again this is a rare commodity nowadays.Sad to say some people compromise their integrity to suit their own set of circumstance.
Common sense is more useful and does not appear to be very common anymore.
IMHO, common sense is intelligence, as opposed to simply being educated or filled with other people's information. Intelligence is being able to take information, introspection, and insight and apply it to life (everyone's life) with the integrity of doing the right thing.
Integrity is when our decision, direction, and daily discipline are congruent with our intent and attention.
Perhaps intelligence and integrity is also seeking without compromise that which is rare but of great value.
