Have you had more success in relationships with people who have careers similar to yours, or completely the opposite from you?

You sometimes meet those couples: two doctors, two lawyers, two writers, two politicians. Do you think it’s an advantage or disadvantage to date someone in your same field? Does it mean you’re compatible or less compatible if you do? Issues that might come up are jealousy, competition, working in the same office or company, running out of things to talk about, etc. Or is that even a factor? Is it all about personality and career is insignificant?
