if you take PHD just to involve with academics related job then go for it but if you wanna find job from industry seems quite hard to get job bcoz not all company will hire worker with a high level education qualification. most of them only seek a bachelor degree holder only unless companies that conducting RnD.

it's bcoz of your gf or what? like me,my gf's family really has a bad perception about continuing study. they think if i have a master degree or phd i will earn more than degree holder if working on industry. so many times i told them that i want to continue study bcoz i love it so much not bcoz i want become rich but they still thinking negative..

u are totally wrong dreamer.. if u mean bout something readable subjects like bussiness,management,etc then someone can learn alone by himself.but what about something that need a lot of instruments to make research like engineering,medic,science? u still think they will buy all instruments needed and do self learning? its not about trying to get a piece of paper by universities.

yes,i know its about phd. phd need to do research and write a thesis right? what kind of engineering field you involved?

yes, you are totally right..even if doing post phd also still need a lot of instruments to do research.
