I'm not allowed to curse either and I find it very difficult as well. I try to be mindful of what I say, but sometimes a bad word just slips out and even if he's not around I keep track of what I say and do and report to Master at the end of the day.
We practice DD, so sometimes that means I get a spanking before bed. Actually, often times I get one before bed. LOL I used to curse like a sailor and it's a very hard habit to break.
I don't get daily tasks usually, but every once in awhile I'll get an email telling me to get in the bedroom and in uniform and position within five minutes of us arriving at home or something similar. I have set rules that I'm expected to follow though and consequences for when I do not follow them. We have some daily unspoken routines as well.
Hope this helps. There are plenty of websites out there with ideas for contracts and daily tasks though that you can look into. Just google it, I found Taken In Hand and The Submissive Wife Project both to be very helpful.
