Jane McGonigal

'SuperBetter' is fundamentally about a mind shift. It's about claiming your power to be in charge of how you spend your time and energy, and focusing it on the things that matter the most to you. Focusing on things that will bring real happiness, real well-being.

Although I'm perceived as very optimistic and upbeat, it comes out of being the opposite of that - feeling isolated or lonely, looking for meaning and the kinds of things that ease that suffering in life, and finding them in large-scale social interaction, like theater and games.

What I wish is that people would look beyond the tribbles and see I've written some other books that I really would like people to notice. There's 'The Man Who Folded Himself,' there's 'The Martian Child,' which is about my son and the adoption. There's 'The War Against The Chtorr,' which is my magnum opus, my great epic story.

Working with franchises can be challenging, but at the same time I really did enjoy working on 'Star Wars,' for example, and I have done a lot of 'Dungeons & Dragons' games, but I still enjoy it very much.
