mental strength

British tennis player Katy Dunne discussing the importance of mental strength in the sport. Give the article a read. https://sportsgazette.co.uk/mental-game-key-to-british-tennis-player-katy-dunnes-success/

Does "Next Gen" struggle more with double-faulting than any other generation of players? We've seen a ton from Felix 2A, Zverev, and even Tsitsipas, Khachanov a bit. Maybe I'm just noticing it more b/c I'm working through it currently too but the last few weeks seem like it's everywhere singles...

Only full OE careers, Laver-Rosewall-Gonzales not the subject of this thread. Let the bias commence.

Which do you believe to be the stronger? The will to win? Or the will to not lose? Watching Federer/Nadal over the years, and from my own experience with competition, I adamantly believe you can achieve much greater focus when you are on the verge of defeat, or when you know one more mistake...

I'm curious, we all spend lots of time working on technique but do you find that working on the mental strength is important to make you a better tennis player?
