Reached a plateau, please help!

I'm stuck at the 10-20 second solve time range! Sometimes I get 6-8 and my best is 5 seconds, but that happens very rarely. Any tips to work towards consistent <15 solve times? I feel like I've not improved in so long. Sometimes I'll see a solution and automatically get it but most of the time I have several failed starts resulting in 15+ times. I also keep quitting on harder ones...

I am at around the same position where I usually get solves around 10-30 seconds and get the occasional sub-10 (around one in every 10 to 15 solves; my best solve is 6 seconds). Never give up You got this
