I normally suggest people do some form of the following:
1. Figure out your MBTI code and get the list of jobs associated with it.
2. Go through that list and get rid of all the jobs you are not interested in at first glance.
3. With the remaining list, google about each job and collect statistics about it:
A. What is the starting salary for the job?
B. Is there a demand for the job where I want to live?
C. What is the job like on a day to day basis?
4. Narrow the list to your top 3 choices for careers based on the data you've collected. E-mail, call or meet with someone in each remaining field and ask them any follow up questions you have.
5. Evaluate and choose your path.
I know you mentioned architect, and I happen to know someone that recently graduated and is working at a firm in NYC. I know that he spent almost every minute of his free time working on his projects during school and didn't have much of a life. He then started with a firm, and similar to how beginning law associates get dumped on by older, established lawyers within the practice, he too gets dumped on by the architecture firm. I'm mentioning this because it should be a consideration when you're looking at jobs.
Sometimes getting a job after college in some fields has more to do with your personality and looks. It may not be fair, or legal in some cases, but certain jobs are harder to get unless you look and act the part. Are you the hobnobbing with clients type? Just more things to consider before picking a career.
