Regular routines

After only a week of being a 4th grade teacher a major weakness of my is being revealed. It has been amplified majorly with 21 nine year olds around.  I don't now nor have I really ever had a regular daily routine. 
I never eat at the same time or have an expected flow of the days events. I shower and shit when I need to... taking birth Control was never a good thing because I never remembered to take it. Laundry doesn't have a special day it gets done every week. I don't drink coffee, tea or make my bed regularly. 
I do so many things all the time I just do not schedule them.
This lack of a regular routine has negatively impacted my efficiency and effectiveness.  Going with the flow and I'll go where the wind blows mentality does not work for teaching kids. They need structure, routine, predictability. I need to be better at planning ahead and being prepared.
All things I've struggled with. The challenge of creating structure for my classroom will hopefully spill over to my personal life. Lord knows I need more structure especially for my son.
