You've again sparked quite a few ideas for myself, since I partly identify with it, then again not, which is a challenge - which I like to learn from. I am similar in that I hardly ever start a thread myself, because if I have an open question I search for all background information myself and that gives me the feeling that I can solve and then post the problem myself. However this actually secretly embarrasses me, because I don't want to come over as a know-it-all. And on second thoughts: I listen as close as I can to everyone that asks earnest questions (I'm "a listener" I spose) and that spawns questions in me which I then try to solve and post an answer about. Since I'm learning and have often been able to apply the ideas to myself sooner or later, these questions and actually turn into indirect suggestions/advice for me. Also when I make suggestions to others after having gleaning and sorting loads of information not just this gleaning, but the answering process turns into advice to myself. Maybe you mean something similar when you "often put posts" that you don't want advice - it does confuse me when people do that - contradicting what I said above, because I actually almost always "want advice", even if I don't ask for it. Also there is a social component for me - if "a child" gives me a present which I don't need or want, then I may try to put it to good use or put it away, but I am thankful for it and show that. I also am above being offended if "a child" offers me advice - sometimes this can be hilarious, but I am beyond this becoming a problem for me. So I don't actually understand your examples (ridiculous, ignoring, impractical, pointless, resultless etc.) as well as it not fitting to my experience. If something is like this, I explain it in simple terms, or if not possible just say thank you, I'll think about it. I never end up thinking something like 'why did I did not realize that' and blaming the advice/advisor or myself: Obviously I didn't know it all and just tried it. If I wasn't capable of seeing that other things are previous in the line, but that's definitely not their fault, not their responsibility, it's mine. And my experience is: my friends, altho not knowing my situation or much about fibro gave me excellent ideas which I am still using to this day. Altogether 5x better than seemingly knowing docs, praps comparable to forum ideas. When I first was given a yoga DVD/book by a mate, I put it into the corner - not feeling the least understood. Half a year later and since then, I use those exercises daily. With an open mind but stable principles I try to see no advice as "daft". Each of us is responsible for not ending up carrying the donkey like in Aesop's fable - that doesn't make the suggestions of the onlookers wrong, it just goes to show the complexity of the situation and different opinions.
I confess: Yes, I do get a buzz and feel important when I give advice, I do it for my own sake as much as for the other person. And because I know that and think that is completely OK, I understand when someone tries to give advice, whether it is sensible or not. It is a feeling of wanting to help, to feel good and do some good, also to feel better. It's very hard to listen to people rant and just say "I understand" without offering the hope of an idea. Only when someone says "thanks, but" and that is then ignored and the person and their decision is not accepted, does it get bad. And I'd extend that to inotazo's situation too.
I'd beg to differ on the final statement, if I understood it correctly: I know a lot of people who can start WW3 without advice, but I know no-one who can end it or rule the world without advice.
