You should distinguish learning through relationships (mentors, coaches, teachers, companions, bosses, parents) from all other sources of learning. Unless you are presented with a figure the likes of Marcus Aurelius, you will only be able to get such learning by reading the words of Marcus Aurelius. This isn’t a bad thing, and you shouldn’t always be on the lookout for better people to spend time with. The boxer who stays with his trainer and grows with his trainer at the same time has an advantage. As time goes on, their relationship deepens, and their ability to communicate improves. They don’t have to figure out what each other really means when they speak.
