"In life as in football, you won't go far, unless you know where goalposts are"- Arnold H. Glasgow 

What this quote is saying is that if you want go go far you alwayas need a goal to achevie but like football the two teams have a goal and the goal is to always get the ball to the other side of the feild to make a touchdown thats here goal when they paly just imagain you playing a game or soprt and make your goals and make sure you stay to that good acomplish that goal its going to feel like you made a touchdown or a homerun because you made that goal and acomplished it and if you don't have a goal or where you want to go you wont make it that far.
