Capture Big Ideas in Simple Ways

Don't rely on your memory or BlackBerry to record and capitalize on good ideas. Go old-school with a stack of 3x5 index cards. Carry them with you and, when you hear a good idea, write it down. 

This physicality of the cards forces you to reflect on them at the end of the day, and the act of writing down the ideas helps you remember and process them. Having the blank cards in your pocket is also useful reminder to be looking for new ideas and, most importantly, to listen.
