The proverbial M - rock and a hard place.
I'm at the age where my friends and family would like to see me married. But as you can guess, contemplating an MBA and you realise you can really only have one of those really expensive things (cynical? yes, a wife is expensive).
Personally I work in a job where I am home for may be 6-8 hours max, if I'm lucky. In such circumstances its neither fare to subject your other half to such torture since he/she will have needs

or will your marriage last longer than Kim Kardashian's.
If you are thinking about your MBA constantly, you want that M. Don't think you need to have the wife. Conversely if you think about a wife and kids more than you think about a very expensive piece of paper and a golden rolodex, get hitched.
