Playing more doesnt make you win more
Honestly. Some people climb to diamond quickly with not many games played. Some people only play a few times a week and have good win rate.
This whole thing is mental. I genuinely believe that all this stuff about learning and dedicating time to learning is BS.
You don't read books on how to ride a bike or do anything else. Why is playing league any different. It's all mental. I'm playing more than I ever have and I'm doing WORSE. I was doing better when I was barely playing. I had a better win rate. Probably because I wasn't so tilted all the time and didn't care so much about winning.
TLDR: Game is all mental, learning and playing more (after you know the basics) rarely equate to climbing.
