A couple of quick questions, mainly confirmations, as I think I know the answers...
1. Is it a good idea to do Direct Learning multiple times with the same books? Does it help or hinder? (ie 3 or 4 DL sessions on the same topic with the same books)
2. I am planning on using DL to enhance my skills in computer programming. I have several books on languages that are kind of 'Complete Reference' kind of books with usage, syntax, et al. These tend to be ~1500 or more pages each. Does 1 1500 page book count the same as 3-5 300 page books?
