Man as an architecture student i can tell you. You need a lot of perseverance and passion and creativity for it. Don't get fooled by the misconception people have saying the main thing you need is the ability to draw or technical drawing. After some point in school probably starting from third year you will start using CAD software and your TD skills even though they are still very handy, they wouldn't be of much use. It's the creativity and perseverance. I don't suggest it unless you're absolutely sure that's what you want to do with your life cause if not you will go crazy and probably drop out.
