How do I work on developing my confidence in my career decisions when I feel like sometimes I could be going a different route Am I on the right path??

I started school as an undecided major before becoming a finance major. However,I sometimes feel like I could have made a different choice and pursued an alternate career that would be better monetarily and more fulfilling personally. How do I know I am making the right choice towards my career goals and how do I become more confident in my direction in school?
