Have you been on a bicycle lately? No? Yet, I am sure, you still know how to ride one.
When you ride a bike you have no conscious awareness of your skill in balancing-pedaling-steering-breaking and your conscious mind is free to focus on other things. However, when asked to explain how you do it, you must make your unconscious skill conscious. Now you must figure out how much of what you know will be relevant or helpful to someone else.
Welcome to the mentor’s dilemma.
Being masterful at something does not mean that you know how to teach what it takes become masterful. It means that you have mastered all the nonsense that stops you performing well. This is why the best way to mentor is simply to share what has worked for you.
Which brings me to the critical issue about mentoring. Being a master enables you to mentor others. It does not entitle you to master it over others.
