When I was young I would be aware that a top novelist or lawyer or sportsperson or art restorer had done something special, but I wouldn't be aware of the full extent of what lay behind it and what it took to achieve it.
I never realised what the top novelist had to go through to produce the novel that I casually summed up as impressive or exciting. I imagined that they just sat down, scribbled away for a few weeks, and hey presto a brilliant novel.
I never thought about how hard it was to come up with an unusual and convincing plot, or vivid characters, or a dramatic ending. Or how hard it was to write fluent, smooth-flowing prose for hundreds of pages. Or how hard it was to keep at it day after day without being distracted. Or how hard it was to get your first novel published after dozens of rejections.
The sheer persistence and self-confidence required is easily underestimated. So many people say they're going to write a novel, but they never do.
The same applies to anyone who's done something spectacular or sensational. More and more I appreciate the hinterland of sheer hard work and application and single-mindedness that made that thing possible.
I was thinking all this I watched some of the astonishing Olympics coverage, and I was very conscious of the years and years of training and tenacity that underlie those stunning feats. Utterly mind-boggling.
