The idea of picking a career path can be quite intimidating considering there are so many options available. Here are some things you can think about to help narrow down the search of what's right for you.
What interests you?
Picking a job that interests you is one of the most important things you can do. There's a saying, "do what you love and you'll never work a day in your life" and it really is true. Of course, there will be an aspect of any job that you won't enjoy but overall if you like what you have to do day in and day out then you'll be putting yourself in a much better position to stay in that field long term. Considering you have to work for decades before retiring, it'll be a lot easier to do something you enjoy doing.
Which environment do you want to be in?
It's not just about what you do but also where. It may be that you don't enjoy doing any lab experiments and so a job within a lab isn't for you, or maybe you see yourself in an art studio or an office in the city. Whichever it may be, speak to people from different trades and try to experience various environments to get the best idea as to which one you feel more comfortable being in and would want to spend your time in.
What options do you have?
The subjects you do/the course you did at University can have an effect where you work. You can research into the options you have and see what others in your position went on to do, this will give you a better idea on the various paths that you can take after completing your studies. From there you can narrow down which is best for you in terms of interest, environment and even location.
Make sure to spend a fair amount of time exploring all the various avenues that are open to you before picking one. It's best to have a good idea of what you're pursuing before you decide to go full force into it. The last thing you want to do is regret your decision!
