Cover art for -1 lyrics by Mudvayne

the song is about feeling worthless. Realising that everyone around you is just so much happier/better/successful etc. than you in every way. And all these people just try to bring you down and make you feel even worse.

@blacklabel1 I don't know if theme follows that others try to bring him down, but I get the impression more they are sick of others telling them how to "better themselves" ... he just wants to be left alone, as shown by the line "Don't need you to tell me how to live".
