Applied knowledge is the real, true power. Do you agree?

The saying "knowledge is power" (or rather, knowledge alone is power) is not true because when you know something and don't do anything with that knowledge, it's useless. And then you ask yourself "Why spend so much time on something that isn't going to be useful to me right away?" For example, when driving around a city area, if you know the traffic patterns during different times of the day, you'll make sure to avoid the areas that get congested during those times (6:00 a.m.--10:00 a.m. and 3:00 p.m.--7:00 p.m. for example) and take alternate routes. It's always good to travel before and after "rush hour" since this makes your trip easier.
