There are lots of people that really think that, and it's sad.
It's easy to be a cheerleader or a critic. A cheerleader sees only the good (intentionally or otherwise) and cheers you. A critic tends sees the worst and attacks you. A coach sees the potential in you and tries to develop it. I see
@mrblaine as a coach and a teacher more than anything. The method of education is unique, but very effective. But one has to learn to listen and understand.
People often say "great minds think alike". I've never understood that. Great minds challenge each other to think differently. The people that really teach you the most are the ones that share your principles but not necessarily your thought processes. The divergence in thinking will lead to new questions and answers and eventually to shared learning.
When I was a graduate student, teaching was part of my duties and I really enjoyed it. Teaching something often forces you to evaluate your own understanding and repeating that evaluation over and over is what really leads to expertise. This type of reflection, learning from past experiences good and bad, is what Blaine tries to impart.
