I'd say its the longest, one of the hardest, most costly degrees you can do. If you did a chart of how many hours you put in, how much work you do, and how much you get paid you'd avoid it like the plague. But we're all nutters and do it anyway!
We know we're going to be poor, skint, nakered and over worked. We're all happy to work 100 hour weeks without gettin paid. We're happy to wreck our eyesight by staring at screens, and become some kind of hobbit / ghost creature like on the Machinist. But that's architecture. I love it or leave it.
Personally, I love the thrill and the lack of logic to study it, its about love passion desire, it tests you to the limits. But anything like art/acting/film making is always going to be something you enter into because of the love rather than some kind of gain.
If you want wedge go into economics and get a job in IB.
It shouldn't seem like a 7 year sentence, rather 7 years of time when you'll be having the best time of your life doing so mething itnerestesting and challenging rather than memorising textbooks like you do on most other bland courses.
It's your life, spend it as you wish. If you've got doubts - don't do it.
