Question about APA paper

I just started in graduate school and have been assigned yet another paper on "my nursing philosophy". However, I've been told to write it in third person. I am open to any and all suggestions. How do I not use 'my, mine, I' when writing about 'my' nursing philosophy?
Thanks in advance from all you nurse educators!
And, yes, I have already emailed my facilitator and classmates this same question.

Thanks for your help. I also heard back from some classmates and my facilitator. Their recommendation is the same as was sugested here; use 'this writer, this nurse, and then she or her'. Someone suggested I write my paper as if I was writing it about my best freind. That helped. So now, I just need to do all my citations and references, since my philosophy isn't based on any of my original ideas! It does feel strange, since we use these terms all the times, to stop and think where we learned them and then give credit where credit is due!

Thanks again for taking the time to help me!
