Start with The Perfectionist’s Anxiety Spiral
This is the clearest place to begin when perfectionism is feeding anxiety, procrastination or repeated checking. It is for the person who can see what needs doing but still feels unable to begin, send, choose or finish until every possible problem has been solved.
The book follows an eight-step framework: notice, pause, shift, decide, act, reflect, repair and sustain. That sequence matters because it gives the spiral somewhere to go. Instead of arguing with yourself about why you should be more confident, you can work through one part of the pattern at a time and choose a next action that is proportionate to the actual situation.
Use it when your standards have stopped being supportive and started making life smaller. You can still value care, quality and thoughtfulness. The work is learning how to hold those values without asking certainty to do a job it cannot do.
