Even if you have the best advice in the world, it’ll be useless if it’s not what the listener needs to hear at that moment.
Might be better to just help them better understand their current perspectives and options. Then they’ll be more open to finding solutions themselves.
When I was in therapy, my therapist would just continually ask questions. And eventually, Id start answering them, and find the answer that I was looking for. It was really amazing.
Now all of my advice is in this way. People already have an idea of what the problem is. Sometimes they don't want to admit it, or face it. But when they talk through it, it's enlightening.
https://en.wikipedia.org/wiki/Socratic_method
Socrates' interlocutor asserts a thesis, for example "Courage is endurance of the soul".
Socrates decides whether the thesis is false and targets for refutation.
Socrates secures his interlocutor's agreement to further premises, for example "Courage is a fine thing" and "Ignorant endurance is not a fine thing".
Socrates then argues, and the interlocutor agrees, these further premises imply the contrary of the original thesis; in this case, it leads to: "courage is not endurance of the soul".
Socrates then claims he has shown his interlocutor's thesis is false and its negation is true.
