oh, this takes some players quite a while.
Everyone of us has their strengths and more weak fields.
On one hand patience is required. Like praticing things you find hard.
But also try alternate ways if you feel like it. Sometimes giving it a rest for a bit rather than trying very very hard.
Personally I think, getting a Uke and learning a few songs on this is easier and at the same time gives you some help with the guitar.
But a similar thing (making the task easier) is what Justin recommends as eg. strumming with muted strings, just for the rhythm. Even along a song you like (“HIde your love away” for 6/8s eg.) any waltz song (but ok - which is better not too fast, the above is quick, I think)
If for me, anything feels hard but I rate it important, I try to dissect it and train on just bits of the thing, and slower also, and slowly add it together over time.
Sorry for the long writing, I hope there was something in it that made sense to you.
In any case, you found a great guitar teacher in Justin and a nice community over here!
WIshing you good success!
PS.
There’s also a “safe beginner’s space” here. where you could link your video and ask for further advice, if you don’t want to share a video with the whole community.
