You Have To Consistently Be Successful To Be One Of The Top Players In The World, And Everything Is Possible In Life.

I Don't Think, That You Can Always - You Can Ever - Get Your Game To Perfection, You Know. Only If You're Federer.

In My Case, I Can Sincerely Say That Nothing Is Impossible... When I Was Saying I Want To Be No. 1 Of The World, And I Was Seven Or Eight Years Old, Most Of The People Were Laughing At Me Because It Seems Like I Have One Percent Of Chances To Do That, And I've Done It.

Not Everybody Can Like What I Do, And If You Feel That Somebody Is Coming Up Closer To You And Starting The Rivalry And Everything, You Maybe Change Your Position To Him.

Tennis Players We're Always Playing In Center Courts That Feel Like Arenas. And When We Get On The Court And The Crowd Cheers Your Name Or Salutes You - It's Like You're A Gladiator In The Arena. And Everyone Is Cheering - And You're Fighting, You're Screaming, During Your Strokes - It Feels Like You're An Animal, Fighting For Your Life.
