Every skill has local minima you get caught in early on. You hit a wall where more practice doesn't mean you get better. To get out of it, you either take steps in random directions and hope you get out of it eventually, or someone else (mentor, peer) tells you what you could be doing better.

Yess we need more of us!

I'd love to be included in this or a future starter pack

would love to be included in this, I'm working in speech & singing ML

would be great to be added to this please and thank you
