How much money do you need?

[FMMonty]

With these big payout up to $7.5 Million is the WSOP I was wondering how much money would you need to never work again.

How much money do you need to never work again, live a life where money is not as issue (within reason, as in not buying massive yachts for example), as in you would never worry about money again.

I personally would work on some projects regardless of any money I had, but it would be more of a hobby.

How much cash do you need to live comfortably for the rest of you life.

Lets say you are in the mid 20's

What do you reckon?
