I really don't get the "I should look" part of the chorus. Does anyone mind explaining?

Little by little by hook or by crook Never get nervous Never get judged I'm no idiot I should look

I'm not entirely sure but my best interpretation would say that this person is living a bad lifestyle, not taking notice of people's views or opinions (Never get nervous, Never get judged). I'm no idiot - I should look, could be a reference to this person coming to the realisation that they may infact be being judged, whereby 'I should look' meaning the person should take notice of these views.

When I listen instead of "I'm not idiot/I should look", I hear "I don't know where it is I should look", which sort of makes some sense.
