You don’t have a snail problem, you have a duck deficiency.

I can easily teach people to be gardeners, and from them, once they know how to garden, you'll get a philosopher.

If people want some guidance, I say, just look at what people really do. Don't listen to them that much.

If you let people loose in a landscape and tell them to choose a house site, half of them will go sit on the ridges where they'll die in the next fire, or where you can't get water to them. Or they'll sit in all the dam sites. Or they'll sit in all the places that will perish in the next big wind.

There are only four things in all cleaners - whether it's shampoo, laundry detergent, whatever.You buy them in bulk and you mix them up properly, and they all work. It doesn't matter if they call the stuff ecologically friendly or have dolphins diving around on the label - it still has these damn four things in it. Anything else is just unnecessary additions to make it smell good or color it blue when it goes down the toilet.

Few people today muck around in earth, and when on international flights, I often find I have the only decently dirty fingernails.
