can't say i was ever much for finding the time to do anything i was not paid to do
Well there is someone after my own heart! Its called quiet quitting and involves working strictly to your job description and not doing all the little extras.
Many years ago I was foolish to allow myself to be drawn into being a virtual PA for an elderly neighbour. I ended up doing her shopping, phone calls, life admin etc although I was a non driver and had mobility issues myself.
Now I make sure I get paid for my time from anyone who is not a close friend. I find that an effective way to avoid being guilted into doing things for others (who are never going to reciprocate) is to ask "shall I give you a price?" which usually has them running for the hills.
Like the new neighbout who wanted to park one of her several vehicles on my drive because "I dont have a car". She disappeared pretty quickly when I told her it was not going to be a cheap option.
