when we trying to focus on study,there are lots of thing to distract us.study half way, you will feel hungry even you just finished your food .suddenly you will feel how come the weather is damn hot right now? it's so annoying lar.cause i m headache because of it.later, you will sleepy cause of the weather too and you will try to convince yourself that you are not sleeping well last night , that's why you feel so sleepy but actually you sleep 9 hours already but you will try to convince yourself that i already study many thing, just gimme a break. so just close da book and sleep. the end.
