i mean before i sang i knew i could do it, and i did. i woke up one day in my group home and said to myself i want to start singing. at the end of the school day we got back home and i rocked out in my room and hit high notes way easier than lower notes. circa survive, SWS, ptv type of vibes. i mean didnt randy blyth from lamb of god take death metal vocals as a joke? heard he was at a bar or something and he just did the noises and his friend was shocked at how good it was trying it for the first time. im not saying this happens to everybody but some people know what they already know. i used to play the piano a bit and learned the first day pretty easily compared to the next guy but got bored of it. take this as you please. my 2 cents.
