We all make choices. Choices that change the entire direction of your life for better or for worse.
Some people choose to be Tottenham supporters, and subject them to a lifetime of failure and an inferiority complex when it comes to Arsenal. Glad I made the right choice there.
But it's not just about your choice of football team. It's down to life's very fundamentals: Who you choose as your life partner. Who you choose as your friends. What you choose as your career.
You win some and you lose some, and sometimes you make a poor choice, and life might be charitable enough to give you a second chance.
At the age of 20, I was resolved to join the armed forces. For some reason, I had talked myself out of joining the RAF, talked myself out of going through the officer selection - reasons of crushed confidence - and put myself forward for the Army as a private soldier.
The idea was to head to the Intelligence Corps. Or the Pay Corps. Or Signals. Things were a bit fuzzy in my brain and I wasn't entirely sure what I wanted.
So, I took a train up to Sutton Coldfield, took the selection exams, took the basic fitness test, was asked in no uncertain terms why I wasn't bloody well putting myself forward as officer material, and was offered a place in Her Majesty's Armed Forces.
It was on the train back south that I made my decision.
The carriage was full of my fellow recruits, and they were a bit - to say the least - boisterous. In fact, it was what people these days called "Bants".
And the target of these bants was - as you'd expect - the posh boy listening to Kate Bush on his Walkman who didn't want to be an officer.
After two hours of piss-taking, insults and petty theft from pretty much the worst people in the world, I was resolved. Two hours with my fellow soldier was enough to tell me that they were the last people with whom I wanted to spend the next ten years of my life.
I got off at Reading, went home, cancelled my application, spent the next three years or so doing absolutely nothing in the civil service, then another ten years before decided I really wanted to be a writer,
So, screw you, bants. I sometimes regret not joining the Forces, but terrible people changed the course of my life.
For the better, in the end.
