It Is Very Hard For Me To

I've Realized I Can't Waste Any Moment Being Unhappy.

I've Had A Lot Of Luck. If I Didn't I'd Be Washing Bottles In Russia.

You're Playing Or You're Not Playing. If You're Playing, So Just Shut Up And Play.

Don't Get Too Excited When I Am Winning, And Don't Get Too Depressed When I Am Losing. Just Keep It Cool.

No Matter What Happens, Tennis Is Still Tennis: You Can See A Lot Of Great Matches, A Lot Of New People.
