Gates: >I didn't take a single day off in my 20s.
Most likely this is only technically true because its almost certain he took multiple days off in his 20s. We'd have to look at what Bill means here by working every single day. If he counts spending at least a couple minutes on something work related every day its far more believable than him spending approximately 3650 consecutive days working 8-12 hours or more.
Wodehouse: >with each new book of mine I have, as I say, the feeling that this time I have picked a lemon in the garden of literature. A good thing, really, I suppose. Keeps one up on one's toes and makes one rewrite every sentence ten times. Or in many cases twenty times.
This claim is even more unbelievable. I'd bet the average sentence he wrote wasn't rewritten at all, let alone 10-20 times. I think what he actually means is that sometimes he would have to re-write a sentence 10-20 times.
