This answer is probably coming to you very late. I’m sorry about that! I haven’t been on Tumblr very much, either on my personal or otherwise.
Well, I like to tell stories. I chose architecture because I was fascinated with how architecture/our surroundings is the backdrop for our lives. Each person’s life is a story. I love love love hearing about people’s lives- their history, their minds, their experiences, etc. Architecture allows me to tell stories in a concrete way. I’m also a writer, and I have great love for all art forms because of the stories they tell. You’ll find that a lot of architects have extremely varied interests because architecture is a sort of culmination of all aspects of design and art.
Out of all the disciplines I enjoy, architecture was the only one where I was required to have a degree to practice. So, plain and simple: I chose to study architecture because I needed a degree to practice it. I don’t regret it in the slightest. It’s a little more difficult for me as my mind isn’t entirely geared towards architecture, but I find it very rewarding- especially on the graduate level. I am also in love with the fact that architecture is everywhere. It’s one of the only things that mankind makes that has the ability to last for thousands of years.
I hope this answers your question. The reason for studying architecture varies from person to person, and I’m sure there are other architecture students who are here on Tumblr that could also help!
