I have loads of idle time while commuting. Very often, busses or trains come late or even not at all.
One night last week during the Big Freeze, I was left shivering and stranded on the platform of my train station waiting an extra 20 minutes to go home after work.
I was cold, hungry, tired and miserable.
Suddenly, it occurred to me that whilst things may not be ideal (when are they ever?) this was exactly where I wanted to be. I have a good job in London, with a satisfactory Masters degree in my pocket, get along great with the insanity folks at work, family (as far as I know) healthy and happy, looking forward to a nice little holiday back home in half a year or so, well able to afford small luxuries from time to time, blessed with fantastic friends and got to experience so much in the 26 years of my life so far.
Busses coming late may tick me off, but in the grand scheme of things it is fairly insignificant.
I feel so lucky.
