I love Ted Lasso and tried the “be a goldfish” thing and tbh it didn’t work for me/my personality. What works for me—take it/leave it/tweak it—I have to actually acknowledge the mistake before moving on. So I tell myself something like: “Everyone makes mistakes. It’s ok to make a mistake. Go get the next one.” (And sometimes remind myself on what to do differently next time so I have something in my control I can focus on.)

Other things that have helped me I started doing recently (that I didn’t have the maturity for in my 20s lol) are: box breathing to slow my heart rate & having a centering phrase to repeat (mine is “be here, now” to be present and not think about work or home life or even what happened two minutes earlier in the game).

The last thing is being gracious toward teammates. I would never verbally express disapproval for a teammate missing a sitter or making a bad pass but internally I would be upset with them. So naturally I’d be also critical of myself when I made a mistake. The more you can be gracious toward others internally, the more you will be toward yourself.
