The Timothy Wilson who you linked to is a fraud, hack, cheat, user of women, and an abandoner of family.
For starters, his (once upon a time) latino wife wrote the book in plain english and he took credit for her work, then divorced her, left her with 4 children and went hunting a more white kind of wife.
He is a real slouch when it comes to honoring financial or other agreements, contracts, or covenants. I gagged when I saw which link you used.
