Change Siblings Mindset?

[Parapraxis]

How many therapists does it take to change a light bulb?
- it doesn't matter, the bulb has to want to change.

If they don't see/feel there's a problem or conflict, they're not going to change. If you change yourself, they may change, but we don't know if it will be for the better. They have to see some self-interest in making a change. You could bring in an accountant to explain the books to them and how soon the company might fail, perhaps that will be an awakening.
