I'd love to read it - and yeah, I get how something like that can be a huge undertaking.

Now that I'm thinking about it I realize that I'd really ought to do the same, if only so I can re-evaluate a few years down the road.

One of my favorite quotes goes "It ain't what a man don't know that make him a fool - it's the things he do know that ain't so" - to which I'd add that every year things I knew would become "not so".

That was in a software design context - but it applies to, well... I can't think of what it doesn't apply to.

BTW quote is Banks not Twain - it often gets misattributed. Same era, though.
