Thinking is hard work

When Albert Schweitzer was asked what's wrong with the world, he replied: "They don't think enough." Thinking is the highest faculty of the human mind -- the key to all progress.

History shows in every soil, that those who think rule those who toil.

"Our greatest need is to teach people how to think -- not what, but HOW." - Edison

Many people read a lot because reading is easier than thinking. Thinking is hard work.
