“In life as in football unless you know where the goalposts are”

The quote given by arnold H. Glasgow is a great quote talking about how we cannot go far if we do not set a goal bar. It is also telling us that life is like football because without goalposts you wont know where you are. I think this quote is hard to explain because of how it is already explained. The quote is also telling us to set goal bars so we can not get lost and go even farther.
