These approaches are not a panacea. They don't always work. It's like training a wild mustang to become a saddle horse: over and over again, you bring gentleness and firmness, you rein in fear and fire and encourage peaceful ease.
Gifting yourself comes in many forms, most them in small moments in everyday life. For example, as I write this, the gift is to lean back from the keyboard, take a breath, look out the window, and relax. It's a do-able gift.
Let go into feeling buoyed by the uprising swelling of this moment congealing into existence, endlessly renewed by the next emerging. Open to trusting in this process, like a wave continually carrying you even as it continually breaks into foam.
Some people err on the side of denying or defending these faults (a word I use broadly here). But most people go to the other extreme, repeatedly criticizing themselves in the foreground of awareness, or having a background sense of guilt, unworthiness, and low confidence.
