[I_WantAllTheCockatiels!]

I just got a cockatiel the other day and I don't know how to make him trust me or bond with me. He will eat millet while I am holding it but only that. I tried to get him to eat a sunflower seed from my fingers so I can start working with him but he just ran away and hissed at me... Several times....
How do I get him to trust me? Pls help!!!!!
