Questions

A mentor doesn't suppress questions or worry about them, they encourage them. They provoke you with their own questions.

A question can lead you to far away places, in the world and inside your heart and your mind.  A mentor's suggestion took me to Buenos Aires, for instance. Ten years ago I reached out by email to a stranger with an enquiry not knowing how much it would alter my life in terms of thought and the effect thought has on actions and destiny. Almost the entire relationship, which lasted years, was conducted by correspondence.  

I didn't know this quotation at the time:

“Watch your thoughts, they become your words; watch your words, they become your actions; watch your actions, they become your habits; watch your habits, they become your character; watch your character, it becomes your destiny.”
