Exercising and renewing your mind is one of the most important steps to being all you can be. One method if confronting good wise philosophy. The book of Proverbs found in the bible (or book of Mishle in the Torah) has some of the best wisdom I know of.
With this challenge, I and others will read one chapter of Proverbs each day until we hit the end. Each day each of us will pick the verse that jumps out at us and write a little on it. In this series you can see mine.
