Why tennis is like writing

As I watched the gladiatorial battles at SW19 this week, it occurred to me that tennis players are like writers. They fluctuate between self-doubt and self-belief.

But while we writers despair that what we're writing is rubbish in the privacy of our darkened garret, Wimbledon's finest must fight their internal demons in the full glare of the world's spectators.

I'll take the garret anytime!
