Thoughts after a bad set

I remember playing against a very experienced player who thrashed me badly with scores like 11-2 and 11-3 in every set. In a tournament, what should I be thinking after getting a terrible score in a set? 

Hi Jasper,

I think in that situation, see what you can learn.  Try different things in the 3rd set.  Try different serves and placement or speed of strokes.

Just do as well as you can and hopefully you learn something new and enjoy playing the game.
