Some kinds of advice only work if the person was distraught over the decision already and the device just 'reminds' them in a sense of what's true, or what they've decided.  In other words it comes at the right place and time and gives them confidence about their decision.

Some kinds of advice are more general and apply to the habits of emotional evolution.  They're not always as helpful as you think.. everyone has their path.

Some kinds of advice are probably even more general, such as "don't lie to yourself" and "don't betray yourself." Anything that tells you, in one way or another, to "give more" is bullcrap.  I'm not sure yet which is worse, crap or bullcrap.  I'd want to put whichever is worse..

So regarding advice, well, basically.. i wanted to give advice here but, then, well, things got hairy.  Actually I wanted to give more theory behind it, but basically the advice *I'm* going to give, right now, is that it depends on your intentions.  Things go awry when you buy things with advice.

Even my 'general' advice above..*is* general but could be dicey to say.  I'll just assume that the context was right and the mood was right.  I suspect the main dice is that it makes someone feel like, well, maybe they do that because it's even a potential insult.  And then they have to ask if they lie to themselves.  And then by asking that they have to test themselves.. and to test themselves they create something like an inversive stack.. and then that comes close to defeating the purpose of not lying to oneself.

The betrayal one I really like though, but that could be because it was contextual that I *do* give the general advice.

ps. i don't know if you knew it, but saying "don't be selfish" isn't exactly a way of saying "give more."  it's saying, "give up.."
