third person, second person, first person?

Every time I write a post I think about the perspective.  Should I write, "one" thinks, "you" think, or "I" think?  Many times I write an entire post and then go back and change the person from first to third or vice versa.  I don't want to sound narcissistic, "I" this, when "I" that, and so on.  I also don't want to come across as someone that thinks they know what others are doing or thinking when "you" this, when "you" that, etc.  This sort of thought process lead me to really look at why I make my class notes public by sharing them here.  My intention is not to tell anyone else how they should think, feel, or act. Nor am I trying to gain approval by anyone.  The reason I share is because some friends and family have asked me to share my story and the tools I come across.  It really only makes sense that I write in first person.  It also is becoming evident that I embrace the idea of writing in first person.  I'm considering sharing a little bit more about my story and why I spend so much time in workshops, practice groups, and classes.  Sharing the "why" will make this more vulnerable.  Given the feedback I've been getting, it might be more useful for others if I make the connection to why and how the tools I write about have made such a difference to my story.  If someone else has had similar struggles, then maybe the exposure to the books, tools, etc will be more helpful to their "first person."
Grace in, peace out
