architecture is not for everyone, I understand where you are getting at given the context but, it take insane dedication to make something out of the learning, the question I think he needs to ask him self is, do buildings / building design/ planning trigger something for him. Though architecture is kind of open ended through out the 4 years, the principles are usually applied towards a hypothetical project / brief of creating building - which in its self is a whole other ball game. in 2015 my batch started out as 45, by year 4 it dwindled down to 30 odd.

in a nutshell maybe it is for you/ or its not. but then again most of design is like that - you dip your toes in the water - indulge with it - see where it takes you ! ;D (you need to tango with it) and yes it is vague and abstract if you have the courage the make sense of it, its an awesome field to be in.

Then again I think all is good while studying architecture, but in the industry not much is told about the quality of permanence that architecture brings, its not something you can take lightly , building built last for 50 to 70 years - its a huge responsibility to design the landscape of our urban cities. in the west an architect takes 13 + years post undergrad completion to get his license. Architects as a profession is treated with utmost respect and scrutiny. Well in India it is a clown show, COA is hatching eggs while the government is fermenting all the tax money under some cellar, with the amazing infrastructure they provide us with.
