For a few months at university, I was in the same social circle as Ghislaine Maxwell. I knew her fairly well. At first, it was fun. Then, almost overnight, I saw it for what it was: a networking nightmare of bright laughter and false friendship, with a howling void beneath.

No one gave a damn about anyone else. It was all about climbing the social ladder. I felt I had seen an X-ray of power and wealth in this country: the grinning skull and empty sockets beneath the peachy skin. It was terrifying. It set me on the path I've been on ever since.

I spiralled into a pretty dark place after that. I withdrew completely, and started the process of working out what a good life looked like, and how it could be lived. The experience inoculated me against ever again wanting to live the high life, or rub shoulders with that crowd.

It was the most important thing I learnt at university. From then on, I went my own way, did what I thought was right, rather than what was expected of me. I've made plenty of mistakes along the way, and I still have much to learn. But I'm glad I saw it when I did.
