No it starts with you
learn how to read a book and you might just have a different opinion about every thing
(tip)Start reading the books from the front
read the intro to the book to get an idea what the book is about
then read the next book
pay attention to what you read
and repeat for every book in that old history book
GOOD LUCK it took me quit some time
hope you have the time
maybe spend less time here and read the history book called the bible instead
stop judging others is a good start
