Flexability issues?

I have flexability issues. I have it with our daily and schooling live. I guess cuz I have been an only child and was single up until I met hubby and a little after wards it's been my way. Since he's been gone for half of our marriage it's been my way. Homeschooling my way. I need to be more flexable and going with the flow. So how are some ways for me to do that. One is that it takes us two days to do one day of lessons in both of my 4th and K grade guides. I am a person who likes to keep going until it's finished. I can ready a 800 book in a weekend or keep sewing or knitting until I am done or my fingers ache. I need to change and it's not easy. I am one step closer to chaning, I have am admitting my problem. Oh and my kids have picked up on the my way or no way so that is what has opened my eyes to changing. My oldest takes after her father but the younger two, my evil dual at times, are very much like me.
