Here's the scenario: there's a blank cheque in front of you. A billionaire comes up to you and says "I will sign that cheque after you fill in the amount, but you can strictly only have what it would take for you to retire and never work again - I'm not buying you supercars, yachts and planes!" What figure would you fill in? Do you even have a figure in mind? Have you ever considered this question or a variant of it before? Don't feel you have to post specifics, of course - money's an intensely personal thing, and every lifestyle and situation is completely different! This isn't meant to be some kind of financial voyeurism thread. However, the mere act of asking the question of yourself - and doing a bit of quiet digging to find "your" answer - might just change your outlook on current or future projects and investments... You never know, but where's the harm in trying?
