Mentoring isn’t just about time; it’s a mental investment. The few people I mentor often come to mind frequently. I reflect on our conversations, even though the actual time spent talking is minimal. I take it very seriously and genuinely feel their progress as my own.

I don’t think I could mentor even 10 people without failing. You have to genuinely care about their progress.

Perhaps the author means coaching. That’s scalable. Teach people how to do something you’ve successfully done repeatedly. That’s something I could do even for groups.
