What are ideas, Exactly??

I was thankful to see there are at least some response on my previous "How to get great IDEAS??" post. It was great guys! Thank you all! I wanted it to be more interactive. So guys please send in your comments and suggestions on this as well.

Ok. What are Ideas? Jim Rohn once said “Ideas can be life-changing.” It’s true. Ideas are new relationships between the things we know, to make new things that we don’t know. I’m sure that’s a bit confusing. Let me put it this way. It’s that flash of light that lets you see things in a new way.

So every idea is a new discovery. If you think now you’ll find new wine from old bottles. George Bernard Shaw explained it even better “If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas.”
Mind boggling?? Let me give you a simpler illustration. Just imagine, you have yellow paint and I have blue paint. Take some your yellow paint and some of my blue paint. Mix it together. What do you get? You will then have 2 colours. Yellow and green. I too will have 2 colours, 
blue and green!  This concept isn't that difficult to grasp right?
That's why George Bernad Shaw said when 2 person exchange ideas, each will end up with two ideas each.

Advertising Ideas are the same, they weave words, images and sounds together in new ways every time to excite, entertain and enlighten the people. So how do we get one?? U should get the geist of it by now! =)
