who is impressive RATAN TATA or NARAYAN MURTHY ?

I am like a poor small creature as an ant as compared to these kind of personalities. So how can I talk or comment anything about an elephant or rhino? Who will belive or like if at all we say some thing about these great and successful persons? I think our part in such a thing would be just observe, watch and follow if possible in a whatever possible manner you can. The scale with me is just in few millimeters and you need to measure a lenth in killometers, how could we do that?
