This is a deep exercise to help you visualize your future life playing out. Once you do that, you move away from the zone of vagueness to being specific about your goals.
Better chance of hitting your goals
The roadmap to take you towards your financial goals brings more discipline in savings & spending patterns. You are now more confident of your resources working productively towards your goals.
Plan for emergencies & unforeseen events
An integral part of this exercise is creating a Plan B for you. This includes creating an emergency fund to tackle short term situations like a job loss as well as the right insurance cover to address unforeseen events like hospitalization or death.
Peace of mind
With identified goals & a specific plan towards meeting them, you can focus your energies on your work & family, without lingering doubts about whether you are doing enough.
