I think that your learning at an OK speed. I've been surfing over 20 years and I'm only on about the same level as you. It's a difficult sport. Most important thing is to love it then it doesn't feel like a chore. Keep the videos coming. 🤙
I would add that something a person can do in the off time is practice their standup maneuver. People think this is just something beginners do but I have been surfing 45 years and I still do it. You should be coming off the carpet and your feet should land in proper position every time. I’m 58 and still ride short boards and get my share of waves at competitive spots. Practicing the takeoff had been key.
