Ideally you know what you want to do and then do the degree that will get you there. A Bachelor degree is just the begining..a ticket to the next step...from there you branch out into something that will hopefully get you employed. Some of the professional programs can be entered before you complete your degree..depends on the program, your GPA and for some programs your score on specific entrance examinations.
It is never too late to start but it can be a long, expensive journey if you don't know what your end goal is
