I've heard kids complain endlessly about how difficult something is, how much time it would take, how something is so hard .. and then when they actually did what it is they were complaining about it took like 10 minutes after complaining for 45 minutes or at times 4 hours.
does it matter if someone isn't a virtuoso if they are just doing it for self enjoyment, experience, a hobby &c? rather than comparing oneself to the "great ones". how about comparing oneself to oneself, whether it is oneself from yesterday or 35 minutes ago? it can become very discouraging if one is always comparing oneself to someone who might have innate abilities. can 't draw if my l life depended on it, I played a clarinet throughout grammar school jr high and even took lessons when I was older. I am bad and have no abilities, but my unskilled non ability did not deter me from doodling or making marks or buying a cheap Italian clarinet and once in a while playing it just for fun.
