Our choice of career is determined by many factors, some of which are within our control and some not. You could have chosen it because you liked it and everything worked out fine. Sometime despite your liking a particular career, you will be forced to chose something else because of circumstances. Whichever it is, it can be said that you have 'chosen' the career you are in now.
Likewise you may have chosen a career in nursing because you liked it. Or despite your dislike of it you may have chosen it because of circumstances.
Whatever it may be, share your story with us, here.
