OK...anyone ever see the movie "Mr Destiny"? 
For those that haven't:  It is this guy's birthday. 
He thinks back on his life and does not like what he sees.  He thinks if he had only hit the big home run in the big game, life would be better. 
So he gets a chance to see what it would have been like and of course he decides his life is better as is(do not agree 100 percent but...)
anyway....
Other day I was thinking that if I could go back to the early 90's and not meet my wife and somehow meet KP what would my life be like?  Now of course we all know I am going to say I would love that...BUT...I would always worry about if my step son and wife were OK.   Life was not the greatest for them and my son needed alot of work to get him where he is and*hand planted firmly on my back & patting it* I was the person who did that work.  I stood up to teachers.  I was the tag team partner when my wife had had enough, and her for me.  And I was also a big enough of an arrogant SOB that belived I knew what was best for this kid when the trained educators said no, that I made them do it my way and in 90 percent of the cases I was right.  I also knew when to just back up and let the few I trusted convince me of another path.  Thing is that now he is set in motion and the foundation has been poured and set with him and alot of the house is built, so my work is not done but it is on the way.  But My question is this...could I forget them and just focus on my happiness.  See the reason I bring up the movie is that even though the guy gets the hot wife that is rich, he can't stop worrying about his"other wife", the one he married as a regular guy. 
I wonder if I could?
