Look at yourself...
- What am I good at?
- What do I really want to do?
- Am I drawn to any particular industry?
Many people will tell you that choosing a career is the biggest decision of your life and one of the most important ones. On the whole they would be right but it's your decision and at the very worst you can always change your mind. So treat that as your life line and let the pressure off a little. Just remember all graduates are in the 'same boat' but in being in the same boat also means your all competing with each other!
The most important thing for you if you are a final year student is to make sure you focus on getting the grades you need. You could spend hours searching, reviewing, pondering and applying for jobs at the expense of your studies and arguably getting a career is the next most important step but you need to make sure it's not at the expense of your degree; otherwise the career you wanted may become even harder to attain.
There are factors that come into play when choosing a job such as location, job satisfaction, money, other benefits, career progression. You'll need to analyse all the careers you would be interested in with these factors and then based on that start searching!
