Rafa Nadal is still on everyone's lips after winning his 21st Grand Slam and the way he did, coming from behind in the Australian Open final against Medvedev. What is most praised about the Spanish tennis player is his mentality, and this video of his speech at the age of 14 is going viral because it explains everything about his discipline and effort to be the best. That was in the year 2000 after winning the international tournament 'Les Petits As'. “Now what do you plan to do?” they asked him. "Keep training , this tournament is important, but winning it doesn't mean you're going to be very good," he said at the age of 14.
