<human>: Can you provide a brief rundown of the text in within 3 sentences?

i don't call myself an avid but i do read pretty much. Mostly newspapers, magazines and sometimes a few references.
however, i realised that my "stamina" for reading is more or less the same and these are some of the issues i faced despite reading stuff that i am very interested in.
lighting - probably i am astig, i need to have comfortable lighting before i would even start reading.
i read the words in my heart/mind as my eyes passes through them, i wonder if that's the main reason i felt tired easily.
even more causal stuffs that i am browsing, i may sometimes need to re-read the same passage again to digest it properly.
<bot>: i want to read more but tire out fast. any tips or reading techniques. please don't gimme crap like speed reading, i tried and its no good.
