Please... he also says he is not so good at the guitar...
I understand where you're coming from, let me elaborate. He says that he's not so good at the guitar when he compare himself to the likes of Chet Atkins and others. And about singing he says he's not a singer when he compare himself to the likes of, in his own words, Dolly Parton and others, the people who are famous
because of their singing or guitar playing. And I basically said that with people who think that Mark is a proper singer, one must be crazy to call him a proper singer, because in the list of his achievements singing would be not even in the first two hundreds.
It's vitally important to always know that at any point of life there's someone better than you, so as someone in the worse situation as you. So when Mark get asked about his guitar playing, he thinks of Chet Atkins being on top, and a beginner guitar player at the low point and rate himself above the average, because, well, this is the truth. And nobody here talks about individuality, character or sound. It's just pure self-evaluation.
To tell you the truth, I rate myself as being no guitar player at all. I can play something, but I make basically zero sense out of it. I don't play in bands, I don't write music, I don't teach. I only play for videos and for myself. So that's why I rate myself being on the very deep end of a big ocean of guitar players, because, in the end, it's
true.
