Getting the poem started

I'm a senior this year (WOW) lol. but each year a few of the seniors at my school get to write something for the year book and they want me to write a poem summing but our highschool experience. i know i can do it... my only problem is getting one started im so stuck and dont know where to begin. could anyone help me. please.

yes, Bob`s advice is excellent..

I always base my poems upon one single line=)

thats a really good idea bob. but my problem is i cant even think of a quote or anything.... im totally at a loss for the whole thing. thanks though

thats a good one too. im gonna try and see what i can do.... aint much coming, i think i might jus put the whole idea down the drain and tell em i cant do it

Write about things that's happend in your day, good or bad, Mix them and use some fantasys.
