This is really life's full circle moment to me.If there is any error, please correct it.
I suppose it means that this is a moment at which this person's life came "full circle" -- that is, they in some way returned "back to where they started". I'm assuming "full circle" qualifies "moment", but the sentence seems prone to mis-parsing. Quotes or a hyphen might help: This is really life's "full circle" moment to me.
