sleep. 30 minutes of sleep for a night won't help.
eat. eating dinner at 5:00 pm, missing breakfast the next day, and missing recess and lunch will make you feel terrible. really terrible.
choose what you take in. don't drink Coke when all you had for the day was a small part of a chocolate-chip cookie that you got from your classmate.
your older brother will never understand you.
stay at the internet cafe the whole night whenever you want to avoid the people at your house.
make sure to teach your little sister her Math lessons before you go to bed.
go to bed when you've spent all your money at the internet cafe, and your last choice would be sleeping...unless you want to spend the whole night at the church (a hundred steps away from your house).
love life. be happy that there are people who will always be there by your side.
