People pleasing and boundaries

Hi Brooke,
After doing models and going through the course this month I have noticed I people please a lot in various ways.

I will allow people to interrupt me when I am working, I will not do the things I want , in order to prevent someone from getting upset with me. I also am now aware I approval seek in indirect ways. Always trying to protect others feelings

Is there a graceful way of getting off the phone or letting people know that work is a priority to me and limit interruptions? How can I stop approval seeking and caring more about other peoples feelings than my own and do it in a beautiful elegant way?
Many Thanks!
