When I begin working with my clients, we could begin diving into their spending plan and work out the numbers. However, without finding out their underlying WHY they want to make a change in the way they are dealing with money, they will not make any lasting change.
So, one of the first assignments I give them for homework is to go through an exercise to help them discover their real WHY for their finances.
Having them grounded in their WHY ensures they can stay motivated to make the changes that will last in the long run, no matter what shiny objects come across their path.
