There is something nice about a blank, white sheet of paper. There is nothing there but potential. The same goes for a blank computer screen - just select New... from the File menu, but then what?
It can be intimidating, it can be exciting, but beginning a new project from absolutely nothing and nurturing and cajoling initial ideas into full fruitfulness is what the creative process is all about.
More often than not, it is difficult to kick-start the creative process. I find that on some days ideas just gush out and on others ... zilch! It may be something to do with the barometric pressure, or ambient temperature, or phases of the moon, I don't know, but one thing is for sure, I can't say to a client, 'Sorry, this is all I could think of!' As a design professional, I can only afford to have good ideas - and brilliant ones.
