This is a quote from Baltasar Gracián y Morales, a 17th century philosopher. We like it because, several hundred years later, it remains one of the single best pieces of gambling advice. If you can learn to quit when you are ahead, then you have an excellent chance of being a successful gambler. - “Hoping to recoup is what ruins the gambler.”
Work hard for what you want because it won't come to you without a fight. You have to be strong and courageous and know that you can do anything you put your mind to. If somebody puts you down or criticizes you, just keep on believing in yourself and turn it into something positive.
