To gain a new perspective, use the tools of someone else's trade for a day. If you're an actor, use a friend's saxophone to help you learn your lines. If you're an accountant, ask the technologists in your company if you can borrow some lab instruments to balance the books. If you're a lawyer, write your briefs with colored pencils. Try these simple instrument switches while you generate ideas for your challenge. If you normally work on a computer, try writing by hand. If you typically use a pen or pencil, type. Or, write with a crayon, a magic marker, or a paint brush. Simply using an unfamiliar instrument can change your frame of mind, give you a fresh perspective and unleash a flow of new ideas.
