It's nowhere near as exciting as you think it'll be, or as Zaha Hadid and Bjarke Ingels make it out to be. It's also not as fun as it is in school, you'll spend most of your days just staring at a computer. If you're interested in architecture for the creativity and freedom, just know that you'll only have that when you're in school. That being said I had alot of fun working for Shigeru Ban even though it was 15 hr days. There was more creativity and freedom in his projects because Shigeru Ban is a brand so the clients are more likely to do what he suggests rather than the other way around... and the other way around is how it usually is.
My favorite part of architecture (in the real world) is probably the very beginning, schematic design and working out a general massing, plan and material ideas.
Sorry if I burst your bubble.
