I can say this as someone who has "failed spectacularly." Until you've tried and gotten a taste, you will never understand why people would even bother when the chance of success is only 1%. I can also say I fully intend to do it again.

As far as support from spouses etc., my wife doesn't like the fact that we owe close to 7 digits right now, but she also understands that to me, this is "living."
