About to get my BSN but thinking of getting my master's in OT after

I will be getting my BSN at the end of the semester. However, I am thinking that once I am done instead of getting my MSN I will get my Master's in OT instead. Thoughts? Applications for September '13 admissions due soon
To what end? Do you not want to be a nurse any more but an OT instead? There really isn't enough information to comment or give advice.
