It is my opinion that the Old Testament book of Proverbs is likely the most concentrated source of wisdom available on the planet, today. Whether you are a religious person or not, you will find that this book contains simple rules that lead to happiness, harmony, and success. There are 31 books in Proberbs, and 30 to 31 days in a month. It's very easy to read a chapter a day. Give it a shot.

Some of the verses that stand out to me.
