I love these lyrics of Leonard Cohen's.  Especially the ones "There is a crack, a crack in everything.  That's how the light gets in."  And those that say "we are stronger at the broken places".  To me they sum up the "human condition" and renounce the premise that we, as Catholics, must strive for perfection.  I believe in one of the first slogans I embraced in AA was "Progress, not perfection". And it has worked for me for 36 years now.
