stuck

in the application i am working on right now, it asks me, "if there were no restrictions upon you, what would you most like to do in your life, and why?"
this should be an easy question, no? well, i am at a standstill. i can think of a few, very ambiguous or cliche responses, but they just don't feel right. i can't seem to figure it out. i don't feel like this should be that hard.
it's probably good that i can't ask someone else to answer this for me, or i might try.
