GOAL OF MY LIFE

till now
i just realized that what i want to do in future
i just found it
i guess it's too late to know it
but sometime i think it's haven't late
you still have time to pursue it
but i am afraid if i m failed
i am afraid i can't get it
what should i do

sometime i feel i regret that i take this faculty
but if i didn't take this i probably can't continue that faculty
aaaargggg
