Consulting through conversation should be part of all of our lives. It's not about preempting what advice or insight may need but simply being open with your life so that people can ask for your insight when they are wanting to learn new skills that you already possess, or they are wanting to see changes in their lives that your insights may help accelerate.
Also, be ready to do the asking! If there is someone whose insight you would like, just ask.
It has nothing to do with doing things to others or forcing what is "necessary" on others. At the heart of it, it's simply an honest conversation.
