Guilt and shame are sales tactics.

They are tactics that are used by unscrupulous double glazing marketeers and religious fundamentalists. And occasionally even by people we love and trust. Including ourselves.

If we can be made to feel Insufficient, they (or we) are a good part of the way to making the sale.

For some of us, and for a variety of reasons, it is hard to avoid being made to, at the very least, feel bad about ourselves, even if we aren’t persuaded to buy the product. And this kind of bad feeling can spiral into also sorts of negative emotions, none of them healthy.
In reality the tactics of guilt tripping and shaming are completely immoral.

There will be many good reasons for doing, or not doing the things we do. We should choose those reasons, and completely ignore the rest.

Right now, who we are is sufficient.
