Show what you know and what you don't know

Be generous in sharing your knowledge (without inflicting help). But also be willing to hear other peoples' ideas, build on them, and help others shine. Admit when you don't know the answers; there's nothing worse than a know-it-all who is wrong. Asking for help helps others see you as a real person, and people generally like to behelpful.
