I always save and read through my FeedForward Cards to gather feedback and identify any topics/areas that the group found particularly interesting. When I initally read through them, I try to take some notes and highlight some of the things people were interested in. This helps me with a couple things: #1 it helps me recognize different point of views and areas of interest that I can put bigger emphasis on when meeting with my actual clients. #2 it gives me some excellent ideas on topics I can discuss in my weekly infominutes, coffee meetings, as well as next 7-minute presentation.
I have a few folders devoted to PowerCore - which is where I keep my FeedForward cards... That way I can refer back to them when needed. FeedForward cards are great to gain new perspectives and helpful feedback you can utilize moving forward.
