I think part of it is to become curious about why you’re holding on to whatever it is you’re trying to control and your reaction/response. Spend a lot of time on this step. I’m working on my anger, for example. I get angry when I feel I’m not in control. Sometimes I am able to take a step back and break the situation down. Once I’m able to specifically identify what is (actually) upsetting me, it gets easier for me to let it go. Took me a while because my reaction is still feeling anger, but at least now my *reponse * is way better. (Sometimes. I’m a work in progress.)

Really depends on the exact problem I would say. If you worry about failure, find alternative ways you can approach when you fail. That helped me a lot to free my mind at least a little. But for anything depending on other persons it's a different way.

Thing about this advice is...it's not a solution that you plug in. You know, like, plugging in a toaster to turn bread into toast? There's no such thing as a solution you plug in to turn overthinking into relaxation. Every time you fixate on the HOW, see it for what it is -- a desire for some method you can plug into your life.

I don't think it works like that. It's not a plug, it's a practice. Like tasting is a practice. It's something you learn to do by doing over and over and over. And failing at it over and over. Even today I can't EXACTLY tell if the salt level in a dish is perfect. But I've practiced so much that I'm right more than I'm not. And I'm definitely right more times than I was when I started cooking. You know what I mean?

Just my 2 cents. I'm an overthinker. When I find myself caught in a "I need to control this outcome" spiral these days, I just "play at" relaxing. No method. Just honest trying and seeing what happens. Fuck around and find out, but in a positive way haha. Deep breaths. Noticing my anxious thoughts come and go. Talking to someone about it. Listening to music. Telling myself I'll be okay even if things go wrong. Taking a walk. Some HOW or the other works. And each time I'm practicing "exiting the spiral." The more you exit the spiral, the easier it gets to exit the spiral. With whatever HOW that situation might call for.

Live like how water moves. Instead of resistance try to flow it is easier and brings peace within

Been there myself - if you cant let go now, you for sure can’t hold on forever, so time will let you let go

Have you ever heard the story of Guru Laghima the Wise?

It's not a story the Avatar would tell you.
