It depends on the culture, specifically when you intend on getting married. In a culture where marriage is expected/normal than I suppose it would be helpful. In my culture (upper middleclass American WASP culture) one typically doesn't get married until 30 or later, so being "in love" (AKA completely obsessed with someone) ends up being a useless hinderance in the long run.

It's certainly a hindrance. However, as hindrances to study go, it's certainly the best. No other hindrance is even a close second place.

I do not thank so,
