"You can't measure success if you have never failed. My father taught me that if you really want to reach your goals, you can't spend any time worrying about whether you're going to win or lose. Focus only on getting better." #WednesdayWisdom from the great Steffi Graf. 📸: 1989 #USOpen. _ #tennis #grandslam #flushingmeadows #steffigraf #icon #champion #instasport #instaquote
