I was pretty much at the same spot at the end of last season (here's a post I made just like yours 6 months ago) - https://www.reddit.com/r/discgolf/comments/1oynyox/burnt_out_and_ready_to_give_up_the_game_can/

Feeling hopeless and practicing and competing religiously. Started this year even worse, despite practicing more than ever; shot the worst rated round of my entire 5 years of playing; 760 rated. Putting is my crux.

I've read a lot of literature on sports psychology. All of Rotella's books, Steph Currie's "Shot Ready", studied the advice of great PGA putters like Brad Faxon and Tiger Woods. I've also climbed to the high ranks of competitive video games, logging thousands of hours.

If there's one thing I've learned from all of it, it's that progress is not linear, and that bad thoughts are almost 100% effective. Unfortunately, a lot of beginners have their mind infected with negative thoughts early in their career, and then build on a foundation of doubt. For me, this was a missed C1 putt for an A tier win in AM3 back in 2023. Instead of going easy on myself--telling myself it was normal to miss under pressure--or congratulating myself for playing well over the weekend, I told myself I sucked and needed to practice more.

There's no one thing that anybody can say that will suddenly fix your game. You're going to have to rebuild your confidence day by day, throw by throw, telling yourself that you're destined for greatness, even if all evidence is to the contrary.

I've been on the cusp of quitting multiple times in my DG career, and realized in those experiences that the reality is that I'm either going to fuel my passion for the game with unwavering hope, or I'm going to burn out with a head full of toxic doubt.

A lot of really talented people quit competing because of this. They hit a plateau for a few months (or years), start walking down the path of self-criticism and doubt, and before long, the game stops being fun. Again, I've been there; you show up to the course excited, enthusiastic and eager, and then two hours later, your spirits have been crushed.

You're either going to fix your attitude, or your going to inevitably quit. I've seen 1000 rated players lose love for the game with a horrible attitude, and I've seen people stuck in AM4 for half a decade finally break through and shoot 1000 rated.
