Intimidation

How does one get intimidated by anyone?
a) The person in front of them is BIG
b) The person in front is menacing/threatening in demeanour
c) The person in front of them is Powerful/Omnipotent
So anyway, some folks, who shall remain un-named said "Harish" is intimidating. I do a lot of talking to possible candidates and I've rarely, if ever, I admit, have ever lost my cool. In any case if someone causes me to lose my cool, its a definite no-no. I'm a man of infinite patience with people who come to me and say "I don't know how to do this, I have an inclination to learn, but I need some hand-holding". I've not had any god-fathers, and I've learnt a lot of things the hard way, or through providence (don't ask me how!!) - and I'm eager to share it with anyone who genuinely wants to know how, and has the patience and inclination to learn.
And for all the folks I know out there, have always known me as extremely confident person. Am I cocky? I would like to think not. Cockiness is something that you can't miss - people misunderstand forthrightness and confidence for someone who comes on too strongly. I am not going to apologize for backing myself. As an engineer its a tough world out there, there is a lot of areas in which one's contribution can be measured, and I want to be there when someone decides to sit up and take notice. But I won't sacrfice my confidence, or my humility.
