''  Enthusiasm makes the difference''
      For me what this quote means is that if you're not enthusiast in you're goals or anything you will never achieve it because you're not putting any effort. Probably the main thing in achieving  something is being enthusiast in it. Many people aren't enthused in their goals so they might never achieve it because they dont show that they are actually trying their best. The more enthusiasm you show the easier it'll be to achieve you're goal because you show that you are actually interested of becoming a better person.
