Thanks pikirkool , i appreciate effort writing to me , really ur so helpful , do u believe i can do PHD in psychology and im accountant ?

Hi, i am accountant whom just finished MBA (43 Years ) , my obstacle is deciding PHD field
Simply i have my own framework to be always happy , latter on , i find that framework is applicable for every single human , poor or rich , its applicable for every one have every thing but not happy , l i find it applicable for everyone ,who have nothing , little of my friend had gave me access to their minds and i knew exactly how they thinking ( psychology )they benefits being happier and i benefits being happier and i enjoyed success.
My framework came of deep understand social , managerial , psychology , marketing , cost analysis and religion ( im good reader ) , simply it's a correct decision while we are always missing an important part while we deciding .
In PHD i will enjoy test it .
I believe 40% of framework in psychology 25% management while other Science are the rest
Finally i don't know which direction i go ? how much its hard to do PHD in my framwork ?
