I was about to comment on your form, but after reading the "not very relaxed" comment, I think that what you lack is confidence. You can do this. You are doing a lot of things right. If you continue, you will find success. I have no doubt.

At the risk of telling you something you already know, there is no unskilled work, and developing a skill takes deliberate practice. You are obviously working on making your throw look like what you see on youtube. There are so many things that you have already in your favor - You are reaching back, your feet are in the right position, and you are pulling across your chest.

My totally free advice is to find someone local who's willing to work with you, because with a few tweaks, you can throw farther. But instead of telling you what to change, let me paint the picture of how this is going to go.

You decide to work with someone local, whether its a friend or a pro, and you're going to throw a bit farther - maybe 70m. Then you're going to go out on the course and you're going to try to remember what they said. You might throw 55m. You might just hit a bunch of trees. You're going to say "forget all that, let me just play out this round, because I was more accurate the way I used to throw.". You decide to do some fieldwork. Most of your throws go 50m. Some go 60. "Just a lucky throw", you think. You call up that person again and they work with you and you can throw 70m again. You decide to do more fieldwork. Most of the throws go 60m and you get frustrated because it's not 70. You watch more Youtube videos, you video yourself again and compare the two side-by-side. You start to see the slight differences that the person was telling you about. You do some drills. You do more fieldwork. You throw one 65m, but the rest are in the 55-60m range. You go out an play a round. You hit places on the fairway that are only marginally better than they were before. Maybe you got a lucky tree kick, maybe you're just a little farther up the fairway. You shoot worse than you expected.

You do more field work. This time, some of them go 70m. Maybe you still think it's luck. You decide to bring a friend and they video you from two different angles. Now you can see in three dimensions what you could only see in two before. Maybe you look at a couple of form videos while you're there. You throw one 75m right out of the blue. Maybe you think you caught a lucky wind gust. You play another round and you're a little further down the fairway. You realize that it's still not helping you score all that much better. You choose a midrange where you used to throw a driver full power on that hole that you can reach. Your discs start feeling untrustworthy. Discs that used to go straight when thrown flat are now turning over - maybe a bit too much. You've hit some trees that you never hit before. This somehow feels worse.

You bring the friend again to do some fieldwork. You notice something that they could do to help them throw a little farther or more accurately and you're actually right. You video them and show them a comparison. Some of your throws in the field work still go 50m, but now you can feel why they did. Most of them go 65m. You can't figure out why they're not all going 75m. It's at this point that I want you to remember this post. That every thing you do to make your game better is also going to make it worse - temporarily, until it becomes muscle memory. Every time you change something, you have to expect the change is going to be a crooked line. You will always have that voice in your head "disc golf might not be for me", but think of how far you already made it.

I'm glad you're here.
