I had never thought that after graduating I would be working 9-5. It wasn't my thing either. At some point, I took part in teaching in university, where actually it requires to work more than 8 hours a day; couple hours teaching, then you have to do some counseling, some researches with number of research group and so on.
Sometime I feel so fed up about this routine that I took few days off before restarting everything. What make me stay in the job is because there are so much fun working with the youngster, teaching is actually way of learning for myself too. When they - my students- accomplish something, I feel prouder than they are, I guess :D
But then you have to make sacrifices : load of dirty laundry that you could only do it at night or even once a week, less time for cooking - which I enjoy much , less time for leisure with my family, unless I am really well manage my time, which still far from perfect
I suppose if you love what you do, that doesn't matter ! but 9-5 is usually having bad connotation. People hate their job and wanting to quit it and gain freedom though not many can figure out what they truly mean by freedom and think through of its implication.
sure its true. I did think of quitting in my first years of working, but decided to stay while looking for what actually I wanna be doing. And I end up staying :D
I am happy for you !
