Agreed, interest/passion is important. Unless you get smart and realise your initial choice is hell. Pick a job that allows you to do your hobbies too. Obviously this isn't a real question, a local educated grad never has these options. He's lucky if he works less than the helpers who put in 18-20 hour days. They can both write one short article per year about overtime and get skipped over till the next decade because they didn't learn the skills to stick up for themselves.
