I really wanted to start speedrunning for a long time now, and I have just started now. I have got a (Default) WR in a game called Rock Hopper, because I was the first to do it. And I have also got a WR in Google Snake (Small, 5 Apples) it still hasn't been verified tho. One of my goals is being in the top 10 of Minecraft and being a well-known Speedrunner

Godspeed on your Minecraft goals. Getting into top 10 (for Java) is insanely difficult (afaik). You shouldn't have to worry about becoming a "well-known" runner though. It's not something that you can work towards accomplishing, it's just something that can randomly happen.
