If you are reading Dr Hill,
Please do not stay stuck in that book - THINK & GROW RICH - where
Those 13 principles are shared.
Not his best book at all.
Please read his 16 LAWS TO SUCCESS and his
SUCCESS THROUGH A POSITIVE MENTAL ATTITUDE.
They may, perhaps be out of print, but please look for PDFs on the net.
