There are good reasons that the actuarial profession is typically rated high among career choices.

Actuaries are ranked:
#9 in Best Business Jobs
#15 in Best STEM Jobs
#21 in Best Paying Jobs
#56 in The 100 Best Jobs
Of course, there are plenty of wonderful threads about the merits of rankings here at CC. This is not a single perfect career choice for everyone, just as there are no universally perfect college choices that fit everyone. If your father suggests this as a career option for you, he probably has good reasons for doing so. I am sure he wants the best for you, and he wants to help where he can. Ultimately, the choice is of course yours, but since he is paying for your college, it probably makes sense for you to at least look into this. He likely knows you have the academic chops to handle this - being strong in math is of course essential. He knows you and wants you to be happy - he would not be suggesting it if he thought you’d be miserable at it. But since neither of you know all that much about the profession, thank him for the suggestion, and look into it. Let him know what you find out - this is not a profession for everyone, and there is not an guaranteed path to success and future happiness. But of course, nothing is guaranteed no matter what career choice you consider.
Best of luck to you.
