Final 3 weeks

I decided several months ago that I quit the job at the end of this month and take over my father's job. Now that I think about it, it's very fast that the time goes by. The rest is only 3 weeks and now I'm a little bit confused. I mean, I miss my friends, colleages, senior and junior workers, even as I feel nervous because new unknown job will start at next month. But all I have to do is to hang in there and get better skills with making use of my experience of current work. Anyway, after leaving Hiroshima and away from current job, I'm gonna take couple of weeks off. And I will get ready for the future!
