Writing These Chapters for a Reason..............by Diane Ogden

I have written two novels only to discover I am the Queen of passive voice sentences.  And the Queen of past and present tense confusion.  
This said, please note I am writing this little or big story to PRACTICE past and present tense writing.
Forget the Passive Voice......someone else can do that one for me.   I do wish I could remember Mrs. Covington's English Lit class.  Retention was always an issue for me.  So here I am writing repetitively every day so I can "get it" down pat.  Then go back and fix the novels.  One at a time.
Thank you for any input at all.  Just be nice.
