One of the terrific traits of the twosome will be that they don't want to get to the top on their own marvelous merits- they don't need any help from anyone else. Trouble is, though, that neither of them will be able to live with a failure and if one of them is a roaring rocket and the other a damp squib in the night of life, their relationship won't be a sparkling success. But if they're both cascading catherine wheels, it could be a life of roses for this twosome.
