Declutter to create spare spending money
As someone with hoarder tendencies, retirement became a time to tackle the beast and declutter.
A collection of professional tools and accessories gathered and "retired" to storage over a lifetime of work became assets to convert into cash. This cash then funds new experiments and adventures to try in retirement.
There are new and experienced professionals in your field of expertise that can use these assets. My thinking is that it is a waste to dump them into a landfill, when the tools are still useful, just not to you anymore.
Offering them on eBay at a fraction of their cost helps other people acquire higher quality "tools of the trade" than they can afford, and you have the satisfaction that these assets are being used.
Start with a low initial bidding price you are comfortable with, and make sure you include proper shipping costs. $20 or more shipping costs on a $20 item is not a deal-breaker for an item that will cost someone $200 or more to buy new.
My goal was to get tools into the hands of people that can use them, tools that are a higher quality than what they have, which will advance them professionally. Better quality tools yield better quality work and results.
Plus I cash in return to get some new tools for myself, in areas I've always wanted to work in.
