beat task paralysis

Task paralysis, fear of the white page, writer's block — you name it. But that's just a huge deal breaker for me. I'm missing so many opportunities all the time because I'm choked by my anxiety. Hands are shaky, head is empty and it feels like I wouldn't be able to write a single line for the life of me. I've always been a perfectionist and my expectations from myself ARE HELL HIGH. In my head everyone will laugh and stare. Everyone waits for my mistakes to laugh and stare. I know that's not true but I can't 'unfeel' it. I'm tired and almost worthless at this point. I've figured out 2 ways to help me out of this issue. Both of them I'll for sure struggle with but hope it's worth it.
1. 10-minute rule. Do the actual work or anything complicated for this very short period of time and then stop. Hope it helps working with discipline, focus and anxiety because it will create a productive pattern
2. Fafo. Make mistakes, face consequences, let it all happen and move on, growing confidence, battling perfectionism
