- Skills at one level can become liabilites at the next
- If you know of only one way to do something, you are in trouble
- There is no point reaching higher levels if you haven't collected the weapons along the way (my personal note here is that perhaps you can try)
Paul Erdos:
When I was a child, the Earth was said to be two billion years old. Now scientists say it’s four and a half billion. So that makes me two and a half billion… I was asked, `How were the dinosaurs?’
Later, the right answer occurred to me: `You know, I don’t remember, because an old man only remembers the very early years, and the dinosaurs were born yesterday, only a hundred million years ago.'”
