I use 1-hour-less principle. It is counter-intuitive but since I am not working for any company I can afford it.

Right before the work is about to finish, I realise that it will take me an hour to finish this - I call it a day.

The benefit apart from less stress is that tomorrow you are motivated for your next day's work, you know you can get something done right away without having to plan for anything.

And that 1 hour's work often takes only 30 minutes.
