Silencing the Inner Critic: Cultivating Compassion in Recovery

So how do I use compassion to move from criticism to serenity? Practice, one technique that had come to mind somewhere along the way is if you've ever heard or think of a time when you've heard someone else being self-critical, you know, kind of out loud or like: oh, you know, I made this lunch for us, but it's really not very good. So then, why is it okay for me to say that about myself? Well, guess what, it's not right when I say it to myself either.
