I am more academically successful, always been a high flyer and have a good spread of skills across multiple subjects, am good at lateral thinking, synergising ideas, seeing connections: and I work in an environment where these skills are essential, and need to be balanced with good people skills. However, there are areas where I am aware I am not as strong eg there is a sort of ceiling in my maths ability: somewhere during calculus where I could do the equations etc but had no idea of the point or context.
DH is less academic, but his main subjects are music, maths and languages, and he is a very good musician (though he points out not a genius) Hes a chessplayer, and functions day to day in a second language so well most people dont realise hes not a native speaker. So although he has less outward recognition of his talents eg qualifications etc I think our innate abilities are pretty equal. He has less confidence in his people skills but oddly enough makes a really good manager partly because of this: hes very fair and unemotional, so really good at sorting out conflicts in his work teams.
We certainly complement (and occasionally compliment) each others skills: but share a sense of humour, love of wordplay, tastes in a lot of things so there is always something to talk about. I have struggled in the past in relationships where there is not a similar meeting of minds.
