and as she reaches the final verse her voice turns up a few notches in volume , and with great , deep resonances , she cries out : if you can keep your head when all about you are losing theirs and blaming it on you , if you can trust yourself when all men doubt you but make allowance for their doubting too , if you can wait and not be tired by waiting , or being lied about , do n't deal in lies , or being hated , do n't give way to hating , and yet do n't look too good , nor talk too wise yours is the earth and everything that 's in it , andwhich is moreyou 'll be a man , my son !
