How can I effectively utilize a wall whiteboard for brainstorming and organizing ideas?

To effectively utilize a wall whiteboard for brainstorming and organizing ideas, start by writing down your main topic or goal in the center. Then, use different colored markers to jot down related ideas and connect them with lines or arrows. Group similar ideas together and use the whiteboard space to create lists, charts, or diagrams to visually represent your thoughts. Regularly review and update the whiteboard as your ideas evolve, and consider taking a picture of it for future reference.
