I would suggest a sequel to your first baby. The second one would actually suggest,recommend,guide and advice on how to LIVE each Fundamental Principle & its subsets in all Areas of life.
For eg. Steve could actually tell his readers this time how to apply Truth & its key components i.e. predictions, accuracy, self-awareness etc. in each area of life like Finance, Relationships, Careers etc. Other Principles and its sub-sets can be taken up in subsequest chapters.
Steve can use the feedback & review of readers of his first book & genuine queries from the forum as basis for this sequel.
He could use wisdom of the East, proverbs of communities & nations, quotes etc.
Suggestive title could be "Practising/Living PDSF".
