At what point do you pull the plug?

It’s your car - don’t let it own you or drag you down.
It can be good to let some things go. My buddies that raced motocross bikes had to give that up when they hit 30 years old, but it’s hard to accept this stuff.
I’m thinking that I probably shouldn’t be water skiing anymore, I just can’t afford to get hurt.
Getting rid of a long term project that may never be done can be very liberating. We just don’t want you to do something you regret by getting rid of it too soon.
