Not sure I shared this (old) link
before so here it is.
Yeah, I know the thread reads like obviousness but the source for the quote may or may not interest productivity seeking users but it's hardly written like a common topic. (seeing as it's a book review although you don't need to read the book)
It all depends on how much you believe:
Life Equals Richness
Life Equals Money
Life Equals Having a Home
Life Equals Fun
Life Equals Productivity
...blah blah blah...yadda yadda...so...yeah, this is more of a meta topic.
