He wrote Rich Dad Poor Dad which is a good book with many good lessons. That said I agree with Darth. Many people that say/do things I disagree with have things of value to say or have said things of value. I put him in this group.
If we only listen to those who we agree with 100% of the time we are going to be ignorant and alone. I don't even agree with myself over time. I've thought and said many things in the past that I now disagree with. We are all human. Don't sweat it.
One bit of advice I love from Jordan Peterson's 12 Rules for Life is to enter relationships with the attitude that I can learn something from them. Even if you disagree or think they are inferior. I've found this to be true. Even if it is that I learn why they believe something. Or why they are wrong.
