Overall, I advise people to think through what they like about a field or potential job. What are the things that draw you to them? How does that compare to your skillset and your personality? Ideally, there's a level of alignment with all of these things.
As an example, I knew I wanted to go into technology as a general field as I grew up in the Silicon Valley, but knew I did not want to be a full-on developer or programmer. I took classes in engineering and confirmed that I did not want to be deep in the technical weeds, but I did find a way in the "business" side of tech. That fit my personality and skillset much better. My classes generally overlapped in a manner where I could switch out of the major without delaying my progress towards a degree.
Obtaining internships, talking to others in the actuarial profession, and checking out professional websites such as www.soa.org are some ways to help you determine if the career is right for you. An actuarial career can take many different directions. And one of the things I liked most about the 40 years I spent in the field is how varied my career was.

After college, I found a non-actuarial role in Enterprise Risk Management that better suited my interests but still utilized many of the skills I had learned through the actuarial science degree.
If you are interested in becoming an actuary, research the industry by familiarizing yourself with the Society of Actuaries, the exams you must take, and the different pathways for actuaries (consulting, insurance, financial services, etc.). The most successful students from my class passed 1-3 SOA exams before graduation. This takes a lot of discipline to accomplish but will launch you farther into your career after graduation.
