is creativity only for superbrains or geniuses. Can not ordinary mortals like us be creative? What is it and how to find this elusive thing!

I teach biochem and try doing research on soil actinomycetes and bacilli in a remote corner of the third world. I often wonder can one be creative and original in the midst of so many odds. What exactly is creativity. Or as the zen budhists say: can ir happen! : "sitting quitely doing nothing the grass grows by itself!"
