Once again...Grey's Anatomy as it applies to real life...

"Some people believe that without history, our lives amount to nothing. At somepoint we all have to choose: do we fall back on what we know, or do we stepforward to something new? It's hard not to be haunted by our past. Our history is what shapes us... what guides us. Our history resurfaces time after time after time. So we have to remember sometimes the most important history is the history we're making today." -Meredith on Grey's Anatomy
