I'd change my name from Michael Sean Patrick to Sean Michael, no Patrick.

Simple enough; my parents raised me calling me Sean, but Michael was my first name simply due to the fact that my grandfather hounded my dad that there should be a Jr. in the family, since my brother was named after my grandfather.

Rather than Michael John (after him) my dad named me Michael Sean, then my OTHER grandmother bitched about having -Patrick attatched to the middle, to make it "more Irish."

People get confused by legal documents saying Michael but knowing me as Sean. Credit companies get confused, as well. I have 3 things on my credit report that belong to my dad, one of which has negatively impacted my credit score.
