I largely agree with the cautions and exhortations.
However, RE:
The most prominent book in this marketing blitz, The Law of Attraction, explains that every negative experience, accident, mishap and influence in a person’s world are the product of his own thinking.

SCRIPTURE SAYS: AS A MAN THINKS IN HIS HEART, SO IS HE.
What we think is important. We are responsible to take each thought captive to the will and purposes of Jesus The Christ, by His Spirit’s grace and help.
We must overcome by the Blood of The Lamb and the word of our testimony.
I agree and and the scripture you're quoting from agrees with the danger of the "The Secret"
Pro 23:4 Labor not to be rich: cease from thine own wisdom.
Pro 23:5 Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.
Pro 23:6 Eat thou not the bread of him that hath an evil eye, neither desire thou his dainty meats:
Pro 23:7 For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.
