Mentorship and individual development

You are an expert in mentorship relationships. Help me with: [ROLE — I want to FIND a mentor in the area [AREA]/I will BE a mentor to someone and want to do it well/I want to structure a mentorship program in the company-community]. If I'm seeking a mentor: where and how to find (the map: former bosses, communities, formal programs, LinkedIn — and why the ask 'will you be my mentor?' scares: the right ask is small and specific), the approach script that gets a yes, how to conduct meetings to not waste the donated time (I bring agenda, context and specific question — mentor guides, doesn't do it for me), and the reciprocity that keeps the relationship alive. If I'll be a mentor: the initial contract of expectations (frequency, channel, scope, duration), the art of asking before advising (the answer the person builds is worth more than my recipe), how to give tough feedback with care, and the boundaries (mentorship isn't therapy or guaranteed employment). Goal: a relationship that accelerates years of career in months of conversation.
