"Bad company is like a nail driven into a post, which, after the first and second blow, may be drawn out with little difficulty; but being once driven up to the head, the pincers cannot take hold to draw it out, but which can only be done by the destruction of the wood"

This quote by Saint Aurelius Augustine is an advising regarding the threats of bad business. It is stating that it is very easy to get out of negative firm when it is first run into, however if it is enabled to continue, it comes to be increasingly tough to run away. The quote is comparing negative company to a nail driven into a post. The nail can be conveniently gotten rid of after the very first and also 2nd impacts, but if it is increased to the head, it can only be gotten rid of by destroying the message. This is an allegory for how negative company can become increasingly difficult to get away from if it is allowed to proceed. The quote is alerting us to be familiar with the company we maintain and also to be cautious not to let negative company ended up being also deeply entrenched in our lives.
