A little knowledge that acts is worth infinitely more than much knowledge that is idle.
If to do were as easy as to know what were good to do, chapels had been churches, and poor men's cottages princes' palaces.
Only in education, never in the life of farmer, sailor, merchant, physician, or laboratory experimenter, does knowledge mean primarily a store of information aloof from doing.
The sole justification of teaching, of the school itself, is that the student comes out of it able to do something he could not do before. I say do and not know, because knowledge that doesn't lead to doing something new or doing something better is not knowledge at all.
Today knowledge is free. It's like air, it's like water... There's no competitive advantage to knowing more than the person next to you. The world doesn't care what you know. What the world cares about is what you can do with what you know.
The great end of life is not knowledge but action.
Practical knowledge of what works and what doesn't work is much better. Theoretical knowledge is important, but I think practical knowledge works better.
