So many people put off taking care of their estate, their wills, decisions about their personal possessions for a time in the future. Unfortunately, too many people wait until its too late.
Having worked with many clients who are burdened with the massive amount of paperwork, decisions about what to do with homes, their families possessions, selling items, donating items, throwing away items because their loved ones didn't plan for this day--so now it's on them to resolve. This is a really unpleasant way for a loved one to deal with such difficult tasks when they are mourning the loss of their loves ones.
It's important to plan for the future. Let them know what is important to you and why. What can be donated or sold. What you want for your families legacy. When a person(s) is/are grieving from a family loss, they are not able to make "good decisions" about their loves ones belongings, so usually one of two things happen. They either keep it all (sometimes even spending hundreds if not thousands of dollars storing it for years) or they get rid of it all. Neither of these are good choices, but its not their fault.
Its never too early to make the investment to organize, reduce possessions, itemize your belongings and have those difficult conversations now with your loved ones. Professional Organizers like myself can help make this process easier for your family. You don't need to be in your 70's or 80's to take on these tasks. You can be proactive about it now and get on top of it so its not so overwhelming.
Letting go of belongings is very liberating and will allow your loved ones to be less inundated in the future. You will also be less overwhelmed and it will also likely reduce your anxiety as well. Whether you do it for your own mental health, or to plan for your future, don't wait until its too late.
