I did the 1st 3 pdfs below in only a couple days.

But I know I need to read or re-read a great deal.
I feel very tired from the thought involved.
I must do routine things – such as programming to rest.
Philosophy is so much harder – and most of it is caused by verbal confusions which make no difference except in philosophy.
Thus it often seems not worth the effort involved.
I have to take breaks – it is also discouraging that I get almost no response – though I do see the pages get some hits.
