"Restlessness is discontent and discontent is the first necessity of progress. Show me a thoroughly satisfied man and I will show you a failure."

In terms of playing ability there is nothing to choose between number one and 100. Instead, it's a question of who believes and who wants it more? Which player is mentally stronger? Which player is going to fight the hardest in the big points? These are the things that determine who is the champion.
