Crap Materials

I found that i might just choose some crap materials,
(well...maybe they r not CRAP, but just useless...)
OMG, i have already had litte time at this moment,
how come these can't just stop showing up!
shuuuuuuut!

btw, my 6th sense works very well,
to tell the material that i'm reading useless or not,
if i can't put any word in my mind or spent lots of time
but just finish few pages, then i know what happened,

well...maybe sometimes just cuz i felt tiresome...
