I'm through my first semester of nursing school and really struggled with my "space". During pre reqs, hubby made me an office space in our bedroom. I could close the door and work in there. But, the desk was too small to have the laptop and all my powerpoints and a book. So, I moved down to the dining room during this semester. It's a formal dining room that we rarely use, but it's in the very middle of an open floorplan house. I have a 13 year old and a dog, but no little ones.
It got noisy at times, especially when son and hubby would start dinner. I learned to study around their schedules. I had 1-2 days each week where hubby was at work, my son was at school, and I was free to study. If the house was super quiet, I could get some work done. But, I would start looking around and see how dirty the house was and get distracted. I'd go off to clean something, come back, get distracted again, and so on and so on.
I can't justify driving the 30 minutes to campus to study and the library isn't a place I enjoy, so I have a new plan this year. On my study days, I'm going to quickly clean the house at least on the floor I can see. Get it out of the way, and get down to business. I hope it works.
I hope you can find a plan that's better than studying in the car. I don't know what, but that would drive me crazy. Of course, your car may be more comfortable than mine.
