The wisdom of Avenue Q

In the broadway musical Avenue Q there is a song called "Fine, Fine, Line" The wisdom of the song has become increasingly evident in my life this past week, and thus I though I would share it here.
lyrics:

There's a fine fine line
between a lover and a friend
There's a fine fine line
between reality and pretend
and you never know until you reach the top
if it was worth the uphill climb
but there's a fine fine line between love,
and a waste of time

There's a fine fine line
between a fairy tale and a lie
There's a fine fine line
between your wonderful and goodbye
i guess if someone doesn't love you back
it isn't such a crime
but There's a fine fine line between love,
and a waste of your time

and i don't have the time to waste on you anymore
i don't even think that you know what your looking for
for my own sanity I've gotta close the door
and walk away

There's a fine fine line
between together and not
There's a fine fine line
between what you wanted and what you got
you gotta go after the things you want
while you're still in your prime
There's a fine fine line
between love
and waste of time.

so those are the lyrics... no explanation really... just wisdom I suppose.
