Heya ManBehindTheCurtain,
firstly, 680 is not a bad score. Its respectable and decent.
Secondly, most people on this forum, an in general struggle either in Verbal (coming from eng/finance/IT background).
If you look at your verbal score, its more solid than a NFL linebacker.
So, lets analyse this a bit more. You want 700+ rite. I have attached a xls sheet here (that i downloaded from another thread). If you keep your verbal in shape (just a bit of practice here and there), you can increase your quant to 45-47, that 700 is all yours.
And guess what, most people agree that Quant is slightly easier to improve than Verbal, purely based on the fact that its easier to identify weak areas and work on them. An besides, you are in finance and got an A- in calculus dude, so don't sweat so much.
anyways, the above only applies if you are considering retaking the GMAT. Keep us posted, in the mean time, take your wife out for a nice dinner over a late harvest pinot noir, because i am sure like my wife she had to put up with a lot during the study.
don't sweat,
Peace
