Hmmm well, what doesn't work for you may work for someone else and vice versa, so yeah I believe anyone can give advices if they feel like they can help someone... any try is worth :)

it isn't quite about whether it works for you but if it might help someone else....

You may not be able to solve your problem, but the problem they're having might be one you know the answer to. If that's the case, you give them your knowledge.'

But certainly if you haven't got a clue what the solution is - start by saying that, and then have a chat and maybe the two of you can come up with a theory you can test. You have to be scientific. :)

Sometimes what does not work for one person will work for another. We can always help others, even if we just say "I'm in the same situation you are"

I do it all the time.

like anything else , we are wired humans I can give advice to someone but not myself not all are able to support there ones that just read, others post , others journal I have gotten better just being here at giving advice some learn too some have natural ability, sometimes we answer our own questions without knowing it , like we are family hugs min
