Nothing in the universe can stop you from letting go and starting over.  We start over all of the time.

Each night, we let go when we fall asleep.  Each morning we start over when we wake up.  But who says we have to start over by doing the exact same thing as the previous day?  There are a lot of different ways that we can start over.  We can look at a problem from a different view point, we can take a class to learn more about a subject, we can give up and try something completely new.  Each option is a different manner of starting over.  How are you going to start over today?
