Why am I up?

Our dog Bolt woke me up at his normal time around 4:30 am. Now I can't go back to sleep. I suppose there are a million things I could be doing besides sitting at the computer but I don't want to do them. Maybe I'm just nervous about starting online school on Monday? Which I am but it will be such an improvement for my family in the long run. I will be able to get a good job and hopefully Nathen can go back to school then. I would like to get him a better job. I know it's just not like being in the Navy but I hope I can find something that will make him happy.
