Please paraphrase this paragraph into a short summary..

Good philosophical thinking takes time. Progress in good critical thinking is often very slow. The process of critical thinking can’t be called successful if it efficiently maximizes its inputs and outputs in the shortest measure of time: We do not produce thoughts in the mind like widgets in a factory. The reason for this is because good critical think- ing often needs to uncover that which subtle, hard to discern at first, and easy to overlook. I define subtlety as ‘a small difference or a delicate detail which takes on greater importance the more it is contemplated.’ As a demonstration, think of how many ways you can utter the word ‘Yes’, and mean something different every time. This also underlines the importance of precision, as a good thinking habit. As another example: Think of how the colour planes in a painting by Piet Mondrian, such as his ‘Composition with Yellow, Blue, and Red’ have squares of white framed by black lines, but none of the white squares are exactly the same shade of white. You won’t notice this if you look at the painting for only a few seconds, or if you view a photo of the painting on your computer screen, and your monitor’s resolution isn’t precise enough to render the subtle differences. But it is the job of reason to uncover those subtleties and lay them out to be examined directly. And the search for those subtleties cannot be rushed.
