There are a lot of ways to choose a career. Most of them are bad.
First thing, throw your preconceptions out the window.
Second thing, don’t worry about income when choosing a career.
Third thing, listen to your heart.
Fourth thing, be realistic about your skills.
Got all that? What’s left is figuring out what your skills are (your actual vocation) and what you’re passionate about (the subject of your vocation).
How do I figure out my skills?
What classes come easier to you naturally?
What are you naturally drawn to doing in your spare time?
What areas do you test well in?
What careers naturally match your default personality?
What do others perceive you as an expert at?
What career paths make you feel happiest when you imagine yourself following through with them?
How do I figure out my passions?
