Perfectionism is something that I struggle with every day. It's harmful, static, and occasionally deadly. It has cost me my health and cost me my dream job. It is overwhelming. Now how do you stop it? What I found helps is pretending everything I do is actually something my younger sister did. When it gets really, really bad I try to find exactly what I am hiding. That's what perfectionism is it's a way to hide. I also have a T that I work with bi-monthly.
