Over the years, he has always told me things that no mater how much I reject always win me over to their side. Rules, advice or simple statements they hold true always. For me these are the gospel truth I go back to each time I am in doubt. They are: Never let someone else make their convenience your inconvenience. Familiarity breeds contempt. Take no one for granted - not even me. Nothing ever stays the same. Ceteris Paribus will never hold true.
