i had a meeting down near Buckingham Palace at 10am yesterday so i caught my normal train which got in to Paddington at 7am (meaning i could do an hour's work on the train and feel good about the day before it had even started)

i walked to St James' park where i sat and did another two hours work, but on the way i saw people swimming in the Serpentine. It's part of some swimming club apparently which is only open 6.30-9am
