What this quote is trying to say is being a good person is better than anything you can achieve in this life. Just because you achieve something really hard, will mean you're a good person. For example, a lot of celebrity worked hard to get to where they are now, but a lot of those celebrity are not good people. It's because a lot of them get in trouble with the law or they do something inappropriate. Another example is when a team wins, but they were being unsportsman like the entire time.
