I found these insightful words on Andy Bachman’s blog. He is the rabbi at Congregation Beth Elohim in Park Slope. 

Be kind and honest in how you look at yourself. The Fast is enough
inflicted punishment for one day. Allow the Fast to allow you to focus
on what truly matters: your actions in the last year; your intentions
in carrying out those actions; and what you may do to improve (not
miraculously solve) those relationships in need of healing in the year
ahead.

May each of you have a Meaningful Yom Kippur Fast and
emerge at Havdalah tomorrow evening with Eyes Wide Open and Hearts
Prepared to bring more justice and peace to our World.
