Saying No
The idea
Accepting your internal experience is not the same as accepting mistreatment. Allowing was never passivity.
The reframe
You can accept what you feel without accepting what someone does to you.
The practice
Find the resentment. Trace it back to the no you didn't say.
The question
Which no is overdue?
Real life experiment
Say it today, in one sentence, no paragraph of reasons.
Now close the app. That bit's important.
