Review...Future...

It is an interesting experience when drafting my SOP and Essays. I need to review my whole life from I was born on earth, moreover, I need to plan my future dream in details based on these histories. The process of reviewing my past is a meaningful procedure. Not only do I need to make every my choices reasonable, but aslo to come up with an idea to accumulate all those experiences for an achievable future plan. It is just like to be a story maker, and the main role of this story is myself.
I can't help wonder..., Has everyone, who made decision in his past, thought a future plan afterward? Is there nothing called impulse in your decision?
