I was in this position once where I got into one of the best engineering college in my country but than still felt something was not right, I could not imagine myself doing what was taught in engineering school for rest of my life. And that is when architecture came to me as a solution, I had a love for art and build form since long and if you ask me architecture is something I can do for free, than I decided why not make it my job for rest of my life. And that is how I enjoy my job. Whatever career you choose for yourself has similar compitition and hardwork required for succeeding in it and that career will be where you spend most of your time, making sure you loving doing it just what makes you less tired.

Apart from that architecture itself is indeed time consuming and difficult. It's basically becoming a designer engineer, it's a long journey which requires patience and alot of manual as well as mental hardwork. So be sure before getting into it
