Brian tracy writes really good stuff in his books.
He makes an attempt to get you to believe him through the examples. Most of his methods do work too regardless of border where you are. He is more realistic and does not post garbage of law of attraction. Realistic but not like vaynerchuk.
His "The 21 Success Secrets of Self-Made Millionaires" is a good book to read.
Brian Tracy is one of the most prolific self help authors of the past 30+ years and has a litany of books. I have listened to them all in audiobook format, some a few times they are that good.
