Book excerpt: Extroverts have all the fun. Or so Jessica Pan thought. When she found herself jobless and friendless, sitting in the familiar Jess-shaped crease on her sofa, she couldn't help but wonder what life might have looked like if she had been a little more open to new experiences and new people, a little less attached to going home instead of going to the pub. So, she made a vow - to push herself to live the life of an extrovert for a year. She wrote a list - improv, a solo holiday and... talking to strangers on the tube. She regretted it instantly. Sorry I'm Late, I Didn't Want to Come follows Jess's hilarious and painful year of misadventures in extroverting, reporting back from the frontlines for all the introverts out there. But is life actually better or easier for the extroverts? Do they really have all the fun?
