Finding Time to Write

I think the biggest challenge of any "part time do it for fun of it" writer is trying to find the time to write.
I remember listening to several authors and they said you needed to get up before the crack of dawn, when the house is quiet and write. Most professional writers I listen or read about say that they follow a schedule, just as if they were working at it.
That is my excuse. I can't really say problem since I know it is just an excuse.
I have been getting up at 6 each morning but I find myself reading more that I thought I would.
I still think reading is important so I need to figure a way to crave out a few more minutes each day to spend time writing.
Before Boo came along I had tons of time. But my time playing and being with her is priceless to me. Once she hits the bed I usually am out to since I am old and tired from being up at 6 every morning.
Then I need to fit in exercise as well...oh my!
