Why do I have to plateau?

I have been doing okay with my plan. Better with exercising than eating. And I am getting frustrated with my current plateau. Trying to get my house ready to put on the market is taking up a lot of time. I plan to keep taking it one day at a time and not get too frustrated. At least I haven't gained. Working all weekend throws me off a little off schedule with my exercise. I had hoped to get up early and exercise before work, but I really don't sleep well during the day-so it was a no go this afternoon. I think it would be better to work out when I get home. We will see how tomorrow goes.
