I switched from Comp Eng to Business because I felt like it was a better use of my people skills coupled with my technical background.
I'm not sure what you're looking for when you mean financial literacy--but I still use double sided accounting like a madman for some of my personal accounting (because the online budgeting site I use now wasn't around then).
I can tell you that my business background has tremendously helped in my different career choices. The most concrete/applicable classes I benefited the most from were the business communication classes where writing effective e-mails got ingrained. While business writing is a different style, being succinct helped me out in my master's program where I honed my writing a bit more.
Some other benefits that I can't necessarily pinpoint where I learned:
- Improved presentations (this might be on you to learn, but the opportunity for practice was prevalent in my program).
- Marketing skills - understanding your target market / audience; can support the skill of "reading the room"
- Organizing information like in bullet points (so it can be easily read in something like a forum post--heh)
- Conflict management - I only remember having a roleplay example, but I'm sure some of the points stuck
And I'm sure there's much more.
You'll get out of it what you put in. If you think you'll enjoy it and can knock out your pre-reqs, then why not?!? As a much older non-trad switching into medicine, I've taken the least direct path--but I look at every past experience as something that has led me to who I am and where I am now. But in the end, as other's have previously said--
find something that you'll enjoy.
