I can assure you that your collection of paper on your interests is not uncommon and if it fits in your condo it isn't insurmountable!
My 94 yo cousin died last winter, and she had been sharing just her genealogy paperwork with my brother for several years. Other than a small box of very old original documentsand books, he has reduced the rest to a single flash drive, giving a copy to each of us who is interested. He declined the offer of all her French books (as the last family member of our generation still fluent) as well as a 50 year collection of material on her other interest, Lebanon and it's recent history & politics, (her husband's homeland.) So her kids are left to dispose of 2 bedrooms full of books and papers, as well as all her other belongings.
My Mom, on the other hand, reduced her worldly possessions from 1500 square feet to an efficiency apartment in the last 5 years of her life. Most of the remaining possessions of any material or sentimental value were designated for a specific child or grandchild. The final clearing up was so easy! With that example, I am working about 2-3 hours a week to reduce my store of treasures, paper and books. I actually ,am enjoying have spaces in my shelves and closets.
Are you ready to spend just one hour a week getting rid of?
