For to him who speaks
with the hard of heart
Will chattering ever work ill.

My interpretation of this passage may differ from most (including the author’s, as he was also a wealthy aristocrat), but the meaning I find in it is thus:
Don’t let your insecurities paint an inaccurate portrait of who you really are.
