New Nurse interested in International relations and languages.

Hi.
Are there any International relations professionals or nurses that can help me?
I am a newly graduated nurse and I am interested in doing another degree in International relations and languages.
I am interested in this because I would like to be involved in global nursing and development.

Am I being too ambitious? I am 33 years old and live in Canada.

Thank you for any help/guidance.

Peace be with you...
