Before you can pursue your professional dreams, you should first figure out what you want in a career. Do you want a dynamic career? Do you enjoy working with people? Do you want to travel? Knowing the answers to these questions, and ultimately to what your likes and dislikes are, can help you better figure out what you want in a career.
To help you work through your thoughts, write down what you enjoy doing, your strengths and weaknesses, school subjects you loved and subjects you dreaded, and similarly, past jobs you enjoyed and those you were happy to be rid of.
