Re: My wife is driving me nuts. Help me!
You may be able to get her to change, but it would mean taking a completely different tack from the one which most people look for – which is probably the ultimate logical argument that will get her to realise that she's wrong. In this case, it seems to be about the odds of winning.
She's doing it for a reason which makes sense to her on some level. Find out what that reason is. To find out, you might have to listen without judging, which usually isn't easy. You could start by asking, "If you win the lottery, what would you get that you currently don't? And what would that mean to you?" and so on.
Once you have that information, you can work out a way of getting that. A way that works well for both of you. Again, it involves being willing to listen without judging.
E.g. for some people, winning the lottery means not being stuck where they are. Fortunately, there are other ways of getting unstuck that don't involve lottery tickets.
I'm not saying it will be easy. It won't be. Is it worth doing? That's up to you to decide.
Please, people, remember to BACKUP before you install that new system. Same if you're upgrading.
