30 days to think about pride

Pride is considered one of the seven deadly sins because

It glorifies oneself and not God
It is selfish
It rages against all wise counsel
It is not submissive to authority
It is judgmental
It leads to discrimination

For sure!

"In the Bible, the first sin committed by human beings, often referred to as the original sin, was rooted in pride. Adam and Eve's disobedience in the Garden of Eden came from their desire to be like God, to have the knowledge of good and evil, and to assert their independence from Him."

So, it may be good to have 30 days devoted to remembering the failures and unhappiness caused by pride. Especially that part about wanting to be like God.
