Your previous accomplishments should be your stepping stones, you need them to jump up. They should not become beds that should keep you comfortably sleeping.
Until you get enough of enough, the enough that is never enough, you dare not quit! If your good is better, your better can be best; your best too can become excellent!
No matter how hard you think that you are pushing, there is always more left in you to turn your drive up a notch. Vow to continuously impress your inner positive self.
