Okay, so you were talking about gratitude. Yes, gratitude counters resentment (you call it "escaping" it). Yet my point was that it is not a cure for resentment; merely a palliative.

Life is a constant stream of potential causes of resentment. Gratitude is not just a palliative for resentment, but also a preventative against future resentment. If you're heavily focused on how grateful you are for the amazing life you live, you will be less likely to fall into a cycle of resentment about the setbacks.

Life is a process of looking for palliatives until we die. Let's not be dishonest about that.

Besides, the only people who promise cures for resentment, etc., tend to be religious.
