The bloke who lives next door but one to my parents studied finance, and is bored tit-less by it daily, being an engineer at heart.
He 'resolved' this by doing short spells of highly paid financial consultancy, before sacking it of and messing about with boats/tractors/welders until the money runs out, and he goes the cycle again, and has found a suitable tollerance wife who can cope with that! That's a very simplistic and harsh analysis of what I have seen and read between the lines. But even that shows that even if you 'do the wrong thing' life continues. - My uncle did Chemistry, hated, didnt do great, and then worked in production/polymer engineering all his life. Obviously as an engineer, coming for a family with a history of of engineers, I see and become freinds with engineering type people. But then again, you can do finance with an engineer degree much better than you can do engineering with a finance degree.
Engineering is mainly blokes, yes, if you do it, you will suck it up and get on with life.
After far as I can tell, and my experience goes, relationships rarely start from a night clubbing.
