Something interesting from my big brother Seth Godiney, a very short post indeed (see, even he does it, so it's ok!) in which he ponders which comes first, success or intellectual curiosity (as expressed in reading books and, nowadays, blogs). I tend to think intellectual curiosity comes first and in fact needn't necessarily be followed by 'success', whatever that means.
But I take the point, all 'successful' people (by which I mean people who are truly human, not that necessarily make a lot of money or have a big, important job, though it's ok to do these things if you want) are intellectually curious, of that there's no doubt in my mind.
