If you don’t take caution in the pursuit of your goals, an accident is most likely to occur, and when it does, it might land you in the DEN.
A den here is a place where goals, talents, skills, intellect, aspirations are eaten up. When thrown in a DEN, that might most likely be the END. This is why a brilliant student will end up as a branch manager of an organization and in a bid to achieve his goals overnight gets involved in a fraudulent act and once caught ends up in a prison yard never to return.
Pursue but take caution, that extra speed might land you in den from which you may never return.
