Btw Buffett's mentor did not hire him even though Buffett wanted to work for free. He later offered him a paying job.
TLDR; No one's advocating working for free. The Warren Buffett approach is "trade money for time with a good mentor."
And I don't know about you, but I can't buy food or pay rent with "time from a good mentor."
Perhaps I could use some mentorship from you. =)
As someone who comes from a poor family, couldn't afford college, and went the mentor-with-free-work route instead, your comment is particularly and hilariously myopic. :)
And tell me, how did you eat while going the "mentor-with-free-work" route? How did you put a roof over your head? If the answer to those is "family", then you're not one of the people that my comment was about.
Are you advocating against mentorship as a principle?
