It's 99% Mental

Summary

Damon Valentino, a sports psychologist, former Michigan State D1 player, and Director of Mental Fitness for the PTPA (overseeing the top 250 ATP/WTA players), joins Lisa Stone to discuss the mental side of junior tennis. The conversation covers when to start mental training (as early as possible), the science of choking and how to combat it, the critical role of between-point rituals, how parents should behave in the stands and on the car ride home, identity fusion in high-performance junior players, and knowing when it might be time to step away from the sport. Damon offers a discount code for ParentingAces listeners on his services through Side Street Performance Coaching.

Guest Background

Damon Valentino grew up in Michigan, was nationally ranked as a junior (contemporaries include Agassi, Sampras, Martin, Courier, MaliVai Washington), played D1 at Michigan State on a full scholarship, briefly played the satellite tour, then spent a decade in high performance coaching before returning to graduate school for a master’s in sport performance psychology. He is currently Director of Mental Fitness for the PTPA and runs two businesses: Side Street Performance Coaching (high performance model) and Mental Fitness Programs (holistic training). He experienced the “yips” as a teenager, which fueled his lifelong interest in the mental game.

Key Topics

• Start Mental Training Early: Mental skills should be embedded in training from the beginning (age 9-10), not treated as a fix for problems. Age-appropriate focus on controlling attention, understanding emotions, breathing techniques, and body awareness.
• Rituals as Strength Training for the Mind: In an era of constant distraction, rituals help set intention and coach the brain to prepare. The “zip of the bag” as a cue to enter tennis mode. Between-point ritual: feel (5 seconds) -> monitor (body check) -> control (conscious breath) -> plan (next point strategy) -> engage.
• The Science of Choking: Choking is the brain trying to protect the person by overriding intuitive muscle memory. Like trying to consciously instruct yourself to walk step-by-step — you’d fall over. Solution: “Regulate first, solve second.” Give the brain a job: check in with the body (heartbeat, tension, breathing) rather than trying to fix technique while panicking. Peripheral vision shrinks from 180 degrees to 30 degrees in panic state.
• Parent Behavior in Stands: Practice coherent breathing (in for 3, out for 3). Focus on attitude, effort level, and problem-solving strategies — not outcomes. Model the next-point mentality. Your nervous system communicates with your child’s nervous system.
• Car Ride Home: Be a parent first, not a coach. Use “it looks like / it sounds like / it feels like” observations instead of “I think you should” statements. Ask open-ended questions. Consider a 24-hour rule after tough losses. Kids may behave poorly in the moment but they are still hearing and feeling your intention.
• Identity Fusion: High-performance juniors often fuse their identity entirely to tennis. When they lose, they don’t just lose a match — they feel like a “loser” as a person. The pressure feels like life or death because the adolescent brain is dualistic (win = more love, lose = less love).
• Self-Determination Theory: Players need autonomy (create their own rules), mastery (learn through failing), and belonging (feel part of something). They need to “reclaim the game” and judge themselves on their own metrics.
• When to Step Away: Look for foundational wellbeing. If wellbeing is shaky despite grinding, that’s the red flag. Use time as a container — “let’s go hard for 30 days and then reassess” or “let’s take 30 days off.”

Actionable Advice for Families

1. Embed mental training from the start — don’t wait for problems to appear. Build rituals, breathing, and body awareness into regular practice.
2. Parents: focus on attitude, effort, and problem-solving when watching matches, not on wins/losses or tactical execution.
3. Practice coherent breathing in the stands (in for 3, out for 3) to regulate your own nervous system.
4. On the car ride home: be a parent first. Use open-ended questions (“What were you thinking about there?”) instead of I/should statements.
5. Respect the 24-hour rule — give space to process tough losses before analyzing.
6. Check in regularly — every 3-6 months, ask your child: Do you still love this? Why are you doing it? Are you willing to put in the work?
7. Use time containers for intensity cycles: “Let’s go hard for 30 days, then reassess.”

INTENNSE Relevance

• PTPA Connection: Damon’s role as Director of Mental Fitness for the PTPA (Professional Tennis Players Association) gives him direct access to the top 250 ATP/WTA players — a unique vantage point on pro-level mental performance trends.
• Mental Performance as Service Category: Side Street Performance Coaching and Mental Fitness Programs represent the growing market for sports psychology services in tennis — a service category INTENNSE should track.
• Identity and Wellbeing Framework: Damon’s framework (identity fusion, self-determination theory, regulate-first approach) provides language and structure for how INTENNSE discusses player development and family experience.
• Parent Education Gap: The episode reinforces a recurring ParentingAces theme — parents need education and tools as much as players. This is a content opportunity for INTENNSE.
• Choking Science: The neuroscience-based explanation of choking (brain overriding muscle memory, peripheral vision narrowing) is accessible, evidence-based content that differentiates from typical “mental toughness” narratives.

Notable Quotes

“Choking is an example of the brain trying to protect the person. The brain wrestles the attention and says, I’m going to override these intuitive muscle memories because this is such a huge moment.”

“Regulate first, solve second. If we’re in a panic state and then we’re trying to solve the problem, we’re trying to solve the problem in a panicked state.”

“If we give them more adoration when they win and then we’re real quiet and we’re sitting on our hands when they lose, the teenage brain says, when I win, I get more love. When I lose, I get less love.”
