How can I practise my Peaceful Place 20 times a day if I am at work all day? Do I need to use the music
No, you do not need the music. I am assuming that you have built your PP, been there in 3 minutes and that you have practised porpoising - now you want to make PP a habit. At work there are many places to practise, some of them can be really useful too - places like: just before you make or just after you have made a telephone call, at your computer, before or during a meeting, before you interview someone, as you switch focus to a new task, at any break (including the toilet) - are you getting the idea? The main thing to work on is a number of ways that you can remind yourself to do it.
