One of the best uses for a Second Brain is to collect and save the scraps on the cutting-room floor in case they can be used elsewhere. A slide cut from a presentation could become a social media post. An observation cut from a report could become the basis for a conference presentation. An agenda item cut from a meeting could become the starting point for the next meeting. You never know when the rejected scraps from one project might become the perfect missing piece in another. The possibilities are endless.
