HellooOo0^^O
Thank you for this special thread that deserve a conversation well Reading is so interesting wether if you are a student, Teacher or even a Jobless reading is like food of the mind so as you give eating a programme you ought to give your mind a programe How?
To read in a moderate way that your mind will bear and comply with. it depends on you if you find yourself understanding and reminding everything you read its okay if you read fast but if you discover that you can't read quickly you need more time just read slowly and in my opinion the good reading is the slow take your time see how many pages you could read per day if the books is for about 400 pages just divide it into at least 15 pages per day I guess it's not that hard then 26 days passes and your book is finished..
Well me I'm the fast kind I read quickly In Ramadan I read Two books In Arabic the 1st one was a Novel for about 450 pages it took me a week but I did not read it regularly
1st day (20 pages) 2nd (50 pages) 3rd (100 pages) like that I remember that I read 100 pages yes coz I wanted to know the events of the novel 
the 2nd book I finished it in 3 days it was for about 250 pages
when it comes to English books I find a lil difficulty but the same rhythm 2 weeks as fast reading 3 weeks as a slow reading but the problem is that I don't read too much but when I read I over it. the single advice that I want to pass here is try to find pleasure in reading a book and you will see how much you get addicted to the book you want to read.
