How Much Knowledge Is Enough?

Life is a balance between not enough and too much scarcity and excess. But my opinion is that now, with regard to information and technology, we exist on the too much side of the spectrum. Without it, one cannot go on too much of it. However, can sink a ship or flood a building. Too much is disastrous. And you cano pretty much fill in the blank with anything else here to demonstrate that point. This is about so much more than picking up phone o google information. It's about never feeling like we're equipped enough to step into something new because we can always be obtaining more. Where do you draw that line?
