I Am...

i am a textbook

i impart much wisdom 

yet heed little

i am a bolted door

i keep others out 

yet fail to progress

i am a a boot print in falling snow

i attempt to influence 

yet leave no lasting impression

I am a cymbal

i contribute my part

yet dread the music's end

i am a mighty oak

i protect others

yet leave myself vulnerable

i am a a mausoleum

i am strong on the outside

yet decrepit within

i am a key

i offer others solutions

yet my own uncertainties remain

i am a soft breeze

i am tangible

yet undefined

i am an ocean

i am multitudinous 

yet am dwarfed by the cosmos
