After being an Impressionist, Cubist, and an Abstract Expressionist, I was influenced by realistic artists, including Andrew Wyeth in the late '50s, and I haven't changed my style since.
Children don't play outside enough. For hundreds of thousands of years young people spent time outside - until 15 years ago.
Aesthetic pleasure is not to be taken lightly; it's very important for the spirit and therefore the health.
My art collection is dominated by tribal art from Nigeria where I taught school, from New Guinea where we've travelled, and by Canadian Haida pieces. My own art is either on exhibition or owned by other people!
I got serious about painting at 12, when most people give up.
When you get to be my age, you begin to count how many Mays you have left - the best time of year for flowers and birds in North America.
The most important question facing the planet is: Is it worth it?
In art and science we are now in a delta, at the end of the long flow of progress. In a delta there is no clear direction but there may be many choices. The best we can do is to enjoy the choices that we have and to be genuinely and creatively eclectic.
I can't conceive of anything being more varied and rich and handsome than the planet Earth. And its crowning beauty is the natural world. I want to soak it up, to understand it as well as I can, and to absorb it. And then I'd like to put it together and express it in my paintings. This is the way I want to dedicate my work.
I take two walks up hills each day, and bike ride each morning. I also have an exercise bike to increase my heart rate. My wife and I have been going to a personal trainer for weights and balance twice a week for 10 years. My balance has improved tremendously and the weights decrease my age. I only feel 52, not 82.
Blackwater USA has already taken in more than $1 billion from the public coffers. All in all, that's not a bad take for Erik Prince, the founder of Blackwater and a Naval Academy dropout who served less time under the colors of the nation, in uniform, than my most recent pair of boots.
I've never thought sitting around worrying helps anything, except to help shorten your life.
Art is challenging and frustrating but I don't linger in it. I work on five paintings at a time so if I'm frustrated I put one down and begin another.
If I ever have a conflict between art and nature, I let art win.
To me the most important thing in a piece of art is the thought. Technique is totally secondary.
It doesn't take more skill to paint hundreds of strokes rather than one right stroke but it takes more patience.
You begin paying more attention to what you're seeing when you know the names... If you don't know the names of plant and animal species that share your neighbourhood, you don't care about them and can't protect biodiversity.
A muse comes down from Mount Olympus and changes my attitude, cheering me up - it's an inner intuition, suddenly giving a breakthrough to be able to move ahead.
If you find yourself worrying, go outside, take three breaths, address a tree and quietly say, 'Thank you.' If you can't find a tree, a dandelion will do... Nature is magic.
I never thought that I would support myself with art - everyone in the Group of Seven had day jobs. I became a geography teacher so that I could get free field trips into the wilderness to paint.
In our instant pudding world, everything is sweet, smooth, very convenient and fast. There are lots of assorted flavors, but they're all artificial.
Nature is not a free lunch, but we treat it as a free lunch.
I prefer to hike in nature, give lectures, or be with family when not working.
