"In life as in football, you wont go far, unless you know where goalposts are" ~Arnold H. Glasgow

This quote means that in life in order to be successful and go far you need to have goals. You need to have a goal in order to be motivated to accomplish your goal. You have  to think about how badly you want it. In football there wouldn't be a point in the game if you didn't have goalposts. People wouldn't even try because what would be the point? You can do anything to set your mind to. As long as you try hard and work hard for it. They key is to not give up and to have goals. If you have goals in your life , and you accomplish them you will go far in life.

"Don't sacrifice what you want most for what you want now. Write down what you want most and see it often." ~Peter Vidmar

This quote is telling you  don't sacrifice something you really want to accomplish in the future for something you want right now. It is not worth it. Your future is way more important that just a temporary thing you might want. You might regret it later if you can't accomplish your future goal because of something you did. Something that wasn't even worth your future being sacrificed. For example if you want concert tickets for you birthday to go see  Bruno Mars but then a new phone just came out and your parents make you choose either the concert tickets or the phone and you choose the phone but the phone wasn't even as cool as you thought it would and you regret it. Then you tell your parents you want the concert tickets better they will most likely say no because you sacrificed the concert tickets for the phone. An example of what is the right thing to do would be lets say your friends invite you to the movies but you remembered you have a really important test to study for and your goal is to pass that test then you should stay home and study for that test and not let what you want now affect what you want later on.
