Cut your toenails, play bingo – and drink rum instead of lager. Performers including Marina Abramović, Sugababes, Don Letts and Paloma Faith share their tips

You find out about yourself at Glastonbury. It is a campus bursting with lessons for the body and mind. Maybe you have an affirming experience, where you learn you’ve got way more stamina than you realised, that you are able to let your insecurities go and fully let loose, or that actually you really, really like hardstep and you’re building that playlist just as soon as you get home. Or maybe your Damascene moment is a starker one, where your mental age and actual age collide head-on. For better or worse, you will learn something about yourself. And for life lessons learned this year, who better to turn to than the performers and celebrities at this year’s festival?

Marina Abramović, artist

But I learned that actually it is possible – to keep the energy concentrated of this amount of people in this moment of human history. And this was something that was a huge discovery: that we humans can change the world by just being together.
