busy, but not busy

these days, i often feel i am busy,

but actually, i can finish work (correctly say, it is a training) on 17 or a little later.

so, i wonder what makes me so busy.

today, i noticed one thing about myself.

it is that i often feel busy if there are something to do with responsibility

or something which i do for the first time.

this week, i have a business trip, which is my first trip.

i'd like to be carm if there are something strange with me.
