It's good to have hobbies.

I used to worry that I had a finite supply of ideas, that I should hold on to each of them in case it was the last. But then I talked to other cartoonists, and I realized ideas are cheap; you can have a million ideas.

The nice thing about Squirrel Girl is that she's smart, and she looks for situations that don't necessarily involve punching people all the time.

My first book, 'To Be or Not To Be,' took 'Hamlet' and converted it to the choose-your-own-path format. It was a great fit for a book where you control what happens - a book as game - because the plot of 'Hamlet' is very game-like: get a mission from a ghost to kill the final boss, kill the final boss, and game over. You win.
