The perspective I see is that too much of the sensory information is relevant. I find it very difficult to read textbooks because the implications of each small part are interesting enough for me to have ideas and wonder at the implications. To a point of view I am engaging in the irrelevant in that I am not advancing directly towards the goal of whatever reason lead me to pick up the text. In that respect when I was at university, studying for exams was a fairly futile exercise if my goal was simply to increase my grade. Many years later I find out the things I did discover while studying are still with me.

I have not become wealthy, but I have become enriched.
