Proper warm-up can help get rid of the “jitters.” For many they go
away once you exercise.
• There is a psychological “proper level of arousal” for athletes. Not too “torqued up” but you do need your game face. Different strokes for different folks.
• Psychologically tough people make the best college tennis players.
• What pressure does to the “one-piston” player is amazing. I saw a lot of number one seeds lose in the national tournament due to early round “nerves.”
• If you “hang in there,” it is truly amazing what can happen. Some call  it “momentum” but “pressure” is a more influencing variable. Tennis is truly unique in that “one point can turn the match around.” This is a
“core” belief.
