While I have modled my life after the advice in the book; I have found it was a great 'starter.' Ultimately, 80/20 living is about reduction - less is more - it is just that you focus in the high impact / high value stuff.. and since your values change - so do the things you will spend time reducing.
Additionally, I have had several life coaches now - each which shared many of their own tricks that I have found great value in. So I use those also.
However, if you look at my 'life.org' org-mode file - you will find that I still structure my life around the Pareto principle.
