I think he should be a bit more specific here. Zig Ziglar says: Share "give up" goals with everybody. Share "Go up" goals only with family, friends, and people you can rely on who will support you and not bash your ideas.

So if you want to give up smoking, tell the whole world and they will hold you accountable. If you want invent something new and exciting, only share it with people you know will support you.
