		<p>Look around, look at what we have. Beauty is everywhere, you only have to look to see it. That's the way I look when I get home late; black and blue. All you have to do is let your imagination go wild. We have a fantastic little sky!</p>

		<p>All kinds of happy little splashes. We don't want to set these clouds on fire. I was blessed with a very steady hand; and it comes in very handy when you're doing these little delicate things. It looks so good, I might as well not stop. We need dark
		in order to show light. I really recommend you use odorless thinner or your spouse is gonna run you right out into the yard and you'll be working by yourself.</p>

		<p>Van Dyke Brown is a very nice brown, it's almost like a chocolate brown. We're trying to teach you a technique here and how to use it. This present moment is perfect simply due to the fact you're experiencing it.</p>

		<p>If what you're doing doesn't make you happy - you're doing the wrong thing. We spend so much of our life looking - but never seeing. In this world, everything can be happy. Everyone is going to see things differently - and that's the way it should be.
		And just raise cain.</p>

		<p>There's nothing wrong with having a tree as a friend. Maybe there was an old trapper that lived out here and maybe one day he went to check his beaver traps, and maybe he fell into the river and drowned. Tree trunks grow however makes them happy.</p>

		<p>Let your imagination be your guide. You could sit here for weeks with your one hair brush trying to do that - or you could do it with one stroke with an almighty brush. We wash our brush with odorless thinner. Every highlight needs it's own personal
		shadow. Don't kill all your dark areas - you need them to show the light. Working it up and down, back and forth.</p>

		<p>Don't forget to tell these special people in your life just how special they are to you. The only thing worse than yellow snow is green snow. That's why I paint - because I can create the kind of world I want - and I can make this world as happy as
		I want it. Let's build an almighty mountain. You have to make almighty decisions when you're the creator.</p>

		<p>We have a fantastic little sky! Everybody's different. Trees are different. Let them all be individuals. Just go out and talk to a tree. Make friends with it. Go out on a limb - that's where the fruit is. There are no mistakes. You can fix anything
		that happens.</p>

		<p>You have to make those little noises or it won't work. We have no limits to our world. We're only limited by our imagination. I want everbody to be happy. That's what it's all about.</p>
