"The value of an idea lies in the using of it." - Thomas Edison. If you have an idea but know one knows about it, or you don't make a plan to put it into action, that is all it's going to ever be - an idea. Think, if Steve Jobs hadn't pursued his idea that every household will have a computer - I probably wouldn't be typing this out to you now. An idea can change the world but it can only change the world if it is put into action - so get out there and do it!
