House Cleaning Tips?

What are some of your tips for house cleaning beyond lots of breaks and work at your own pace? I have mobility issues, flexibility issues and am generally REALLY FREAKING SHORT (>5'0) and can't climb or balance on ladders and step ladders. I feel like I can never stay on top of an even semi-tidy home and a flare up will end with a scrap heap that makes me want to cry.

It wasn't so bad when I only lived a half hour from my parents because my mom would come every other week and help me out, but I live an hour and 45 minutes away now and I would have hired a house cleaner if it was in my budget. I'm just so frustrated and could use some quick tips and tricks.
