Sorry for the edit. This may have been a topic before.
I got the idea for this from Crumpets thread "If I could make your dreams come true what would they be?"
I have been asked many times "if I could go back in my life and change it, what would I do?" This is included in the book I am writing.
I know I can't change my fathers life so he will become a JW anyway. For me my answer is this. At the age of four or five, I would on a Sunday morning run out into traffic on Canal St in Salem Massachusettes, in front of the KH, before the meeting started.
How about you? What time in your life would you go back to and change what?
