here's a suggestion. Here's the song I play in the background when I need to let things go:

Giving the ex the smoke, using an urban dictionary meaning.

Now I'm not disagreeing with the(your) shredding
However, I have retained much older receipts
Just as a means of related 'self-assurance'
Even in the very-very unlikely event of
Who knows what OR when (if ever)

My brother called me, Mom still has medical bills from the 90s. He tried to convince her it was ok to shred those, she had a fit with him & fussed about his suggestion to me. Mom is 87, fair bet that we'll be purging that in the next 15 yrs.
Adulting sucks
