please help me
verry verry improtant

honestly, school in itself just seems to be a huge waste of time. a lot of people graduate but still end up not doing anything in college anyways, which really makes the whole point of graduating seem useless. i'd rather not bring anyone's hopes up then. what i'd recommend is for whoever's reading this to simply drop out.

i mean, kanye did it. he said something along the lines of, "don't let society tell you what to do." now, he's obviously a very successful person, and since his album is called the college dropout i guess he never really had to go through all that nonsense in order to become a millionaire. the same goes for anyone else then.

- "the die is cast; i have consented to return if we are not destroyed. thus are my hopes blasted by cowardice and indecision; i come back ignorant and disappointed. it requires more philosophy than i possess to bear this injustice with patience. i have lost my hopes of utility and glory; i have lost my friend."

you didn't show the passage, so unfortunately i cant you.

the purpose is to inform because for some reason they really want you to know about it.
