Train the mind that swings.

A junior tennis player's notebook on attention, pressure and practice — one page before every match and training day since March 2024 — kept next to an AP Research notebook on what the brain does after a blink.

The idea

Every forehand is a memory test.

Cognitive science has spent seventy years working out how attention narrows under pressure, why practice that feels bad transfers best, and how a skill goes from effortful to automatic. Tennis runs every one of those experiments on you, live, in front of your parents.

This site keeps two notebooks side by side: the one from the racquet bag, a page written before every match and training day, and the one from AP Research, where I read the papers. Where they overlap is the interesting part.

Attention

What narrows under pressure, and how to spend the budget on the ball.

Memory

Why a page written the night before holds up better than advice heard courtside.

Motor learning

How a stroke goes from twelve cues to one, and what that feels like from inside.

Match days

Nerves, body language, and what to read on changeovers.

Not looking at the stands

“My dad is here, and sometimes I can put unnecessary pressure on myself to play better when he is watching me. In reality, he just wants to see me compete, carry myself well, and improve.”

Missing with the right intentions

“Yesterday, when I was missing balls with the right intentions, I got discouraged. Actually, I should be happy that I am doing what I have been trying to work on and be even more ready to continue doing it.”

Our own journeys

Level-headed, like the pros

“It surprised me how level-headed the players were. They didn't get super positive or super negative. The entire matches, they stayed positive yet focused.”

Prepared for mistakes

“My coaching voice will remind me to do the ordinary things extraordinarily well, to being prepared for mistakes and recognize they are part of the process, and to enjoy playing, as I play my best when I'm having fun.”

Perspective, then fun

“I will remember that no shot, game, set, or match will be the deciding point of my life. Nothing will happen if I don't hit well, so there is no point to being scared.”

Positivity under pressure

“If I succeed in carrying myself well, stepping in on my backhand, keeping my head up on my serve, and not reverting to pushing when under pressure, I will have a successful match. Win or lose, I will be proud of my effort.”

About

Shaan Prasad, eleventh grade

I've played junior tennis since I was small. In March of 2024, ninth grade, I started writing a page before each tournament and training day — what I would focus on, how I would carry myself, what my coaching voice would say when things went wrong. Those pages are here, scanned and typed out, exactly as they were written, with new ones added as I go.

Now it's eleventh grade and the second notebook is for AP Research, where I'm reading about what the brain does in the split second after a blink. This site is where the two notebooks sit side by side. Nothing is backdated; the handwriting has its own dates.

New pages go up as the notebook gets scanned — a few at a time, oldest first, two years to catch up on.
