Stan Wawrinka

There is always disappointment, heartache. You are losing almost every tournament. You need to just accept it and be positive because you are going to lose and fail. We're not all Nadal or Djokovic, who can win most tournaments.

I always try to find the positives in losing a match, but it's not always easy.

As a tennis player, you have to get used to losing every week. Unless you win the tournament, you always go home as a loser. But you have to take the positive out of a defeat and go back to work. Improve to fail better.
