Traders are typically inundated with information--from charts and data feeds, chat, financial media, social media--but obtaining knowledge (not to mention wisdom!) requires some active filtering. The challenge is to be open to new sources of perspective, but not so open that everything becomes a blur. I would much prefer to deeply ponder five excellent sources of knowledge than skim fifty. Indeed, it's the proliferation of information--and our desire to assimilate it all--that often prevents us from obtaining true knowledge and wisdom.
