Why am I in Japan?

I am currently on the train, so please excuse me if there are any typos or grammatical errors.

taken from my house...

why am I here... what is my purpose?
I have gotten this question many MANY times...

unfortunately, I don't have the answer... I'll be very honest, I really don't know...

How I see it is, instead of worrying and wondering why... I choose to enjoy this place... try to get as much out of it as possible... because I don't even know how long I will even be here...

All I care is I'm enjoying life... perhaps this is the purpose in itself... why must I seek the purposes if I am already living that purpose?
