Completely understand where you are coming from Lea, I think that people can be open to change and take advice without self-awareness. I say that because I went through a long period of time where I didn't have it and still was open to someone else's perspective and experiences. True wisdom can resonate with us no matter what our state of consciousness and I trust that what I need to learn will be there for me and I have that same trust with everyone no matter where they are on their journey.
Either way, if someone asks advice I always give it not only because they asked but because you never know how what you say will affect someone, it might wake them up
