What would ruin your life if your wish is granted?

Doing it all over again from the beginning.

Winning the lottery? Never. I’m sane and disciplined enough not to ruin my life with having too much money. Having the powers of Superman plus invisibility when I want to just might.

No. Unless you mean we have to start over from the beginning. From this moment, I have enough experience to do it right,

Too much money unless planned out well.

Give some to charity.( help relatives in debt)
Save some,
And spend some ( but not overboard).
