It's been four years since I reluctantly let my NRA law enforcement instructor credential and Florida "K" license (law enforcement instructor) and other state licenses expire. It's a long story but in short the state kept adding unnecessary and expensive burdens on me, so the licenses were easier to let expire than renew. I kept my NRA civilian instructor credentials so... dunno why actually.
Not long ago a local range asked if I would teach there again (I taught there 10 years ago) and today a gun store asked if I would teach their CCW class. Both have potential of ancillary things that I may be drawn into.
Here's the rub... I've gotten used to not having a schedule and got re-involved in fishing, shooting, ammo making and gardening and I am hesitant to start again.
Has anyone else retired and gone back to work (not necessarily firearms related) and found that it did not interfere with their retirement lifestyle?
