Rob, aren't you leaving out those who have the desire to create (and maybe but not necessarily, the genes), but lack the technique to do so?
Eduardo, I took that into consideration when I made my point about my failure with music; I have
all the desire in the world to be able to play a Chuck Berry riff even once; I have the talent to carry a guitar, preferably in a case.
It's just how it is: some can do some things well and others can do other things well, but none of us can do it all and making images in any medium is no exception to that inconvenient rule.
However, if there is pleasure in trying, then go for it. But remember, knowing where to find E, A, D, G, B and E guarantees nada!
