I have sometimes done cartoons that are hurtful to people - immature, spiteful stuff. Some are so self-indulgent, and some have just failed. I look back and sometimes cringe. But one regret as I get older is that I haven't been radical and wild enough.

When I look back at the way that I was in that documentary I cringe.

I give thanks for the fact that I can get this stick with a bit of steel nib on the end, dip it in some black carbon stuff, and draw on paper. Now, people did it the same way 2,000 years ago. And there's something lovely about that play, and making mud pies and a mess. That's a lovely privilege.

An education system suits some more than others. It can lead you out into life or lead you on a wild goose chase. It can help to make you miserable, or dull and nasty and insipid, or profoundly stupid in the special way that 'brainy' people can be.

Some guys look better as they get older.

It is home schooling that is rejecting a narrowness. It is not a radical value system; it's actually quite conservative.
