That's one of the best reasons to pursue nursing!
Nursing is it's own profession with required curriculum and licensure.
The list of everything that goes into an RN license looks really daunting and it helped me to look at what's right in front of me and not what's a year or two from now.
When starting college, take the same things required of any degree (English, humanities, etc.) while also looking at nursing programs in your area or are interested in along with their prerequisites and gpa requirements. After English and some other gen ed courses are successfully completed, start narrowing your courses to those fundamental to healthcare (anatomy & physiology, microbiology, chemistry, etc.).
Best of luck to you!
