We just watched "Charlie St. Cloud".  I wasn't sure if I'd like it.  I didn't know anything about it.  Turns out it's about letting go of the past and moving on.  At the end of the movie Charlie says "It hurts as much as the day you died".  Sam responds, "It hurts because you're alive".   We hurt because we are alive.  We love because we are alive. 
There's something comforting about living in the past, like somehow we can fix it.  We can't.  I know that the only way out is to let go and move ahead.  Oswald Chamber says; "let the past sleep, but let it sleep on the bosom of Christ... and step out into the irresistable future with Him."  On a more secular, but true note, Ann Landers says; "Hanging onto resentment is letting someone you despise live rent-free in your head." 

So... 

Move ahead or go back? 
It's time to start looking ahead.
