Since you asked specifically about economic comfort you can do some research on the website www.glassdoor.com to get a sense of what jobs have what salaries.
It is definitely important to have a balanced life. If you work at a job you love but doesn't pay enough then financial troubles will cause stress in your life. Vice versa if you work at a job that you don't enjoy at all but pays very well then you wouldn't have the healthy work-life balance you want.
First recommendation would be to create a list of careers/fields of studies that are interesting to you. It doesn't have to be "the one" at first. Then use the glassdoor.com to see what salaries those careers earn and if that influences your decisions at all. Other factors will affect a specific job salary, but you can get a sense of the average. Then ask yourself that if you really had to choose, which one is more important? Job satisfaction or financial comfort? You can have both but you should have a plan to be able to make tough decisions on hard scenarios.

Since you're doing well in all your classes you have options. The hardest part may be narrowing down your path but it's also an important one.
Best of luck!
