When we ask for help, we tend to unconsciously add unnecessary details that enhance our image, justify or even state a request instead. When asking for help, take the bass out of your voice, the stiffness out of your spine, and the captain out of your industry and just say, with sincerity and humility: "Can you help me?"
Few people, especially face-to-face, will ever say "no," even a stranger.
When you ask for help, you may feel inclined to apologize for taking up their time and energy. Don’t.
This is a bad idea because putting yourself down makes the other person feel less joy in helping you. Many of us apologize too much anyway.
