LOL. If he had $10 million, he would have lost it in 5 years, not 10.
I wouldn't need $10 million to retire, I would do it on $1 million and not work again (yes, I'm serious).
My wife and I don't needs 10 million to retire but we'll have it anyway. Our target is actually 16 million. We hope to retire at 55 (we're the same age) and spend the 30 years following that blowing our money. It should be fun.
