I'm rather ambivalent about famous/successful people who I don't know/care about.
They don't affect me.
Relatively minor things get to me, like for instance - a few nights back I was plodding away on my guitar playing a simple song, or at least, playing a song simply.
I was really enjoying it, tapping my foot. Escaping.
Well, then I youtubed it and saw a guy playing the same song, but shall we say, on another level. Doing way more trickery and getting more impressive sounds out.
And I just put the guitar down and walked off after seeing it. My attitude was "well $#%^, why even bother".
This kind of thing has happened to me before. I was at a party and quietly strumming on a guitar, not performing or anything, just again, escaping and playing chords for myself rather than an audience.
Up steps one of my then friends, asks for the guitar, and off he proceeds to play the same thing, only a thousand times better.
And once again, I think, "well ###$ that, why even bother".
I'm the least competitive person on the planet, I see music as art and simple escapism, and when I perceive (rightly or wrongly) that someone's turning it into a pissing contest, I get annoyed, self loathing kicks in at my own shortcomings and I walk away from the instrument for months.
I've got loads of creative interests; music, photography, drawing and a little writing. But I suck at them all. Seeing the masters do it makes me want to not even try.
