All Comments on 'Advise to the Indicted'

I really like this poem but I think that perhaps there are a few typos, starting with the title, should that be advice?

Should line 11 be 'The definition of failure is sitting rigid in a plastic chair.' By the way I love this line and I removed the first is. And perhaps line 13 should read like this 'You may as well put a plastic bag over your head now' or 'You should put a plastic bag over your head now' Also it is possible that I am dense and am totally missing the the intent of the poem. Well either way I think it is a kick ass poem.
