Retirement isn't what it's cracked up to be. Celebrated my 81st birthday by taking on another deuce ch***is for a friend. That ch***is plus the one I'm already doing just to keep in practice should consume my time for a while? All I told him was hope your not in a hurry. In the 3 years since my last customer ch***is I found it's hard to walk away after 40+years in the business.
Have you considered p***ing on your knowledge/experience so the good work isn't lost when you do eventually stop? I fully appreciate having an employee can be an expensive game, no one local you can collaborate with? Seems a shame for it to stop when you stop as it appears quality and successful work?
Just because you are retired(?), it doesn't mean all you have to do is sit and watch the world go by. To me, it means doing what you want, when you want. Enjoy and share if you like, Carp.
