To be, in a word, unborable…. It is the key to modern life. If you are immune to boredom, there is literally nothing you cannot accomplish.

― David Foster Wallace, The Pale King

People think focus means saying yes to the thing you’ve got to focus on. But that’s not what it means at all. It means saying no to the hundred other good ideas that there are. You have to pick carefully. I’m actually as proud of the things we haven’t done as the things I have done. Innovation is saying ‘no’ to 1,000 things.

— Steve Jobs

Noch so ein Knuth Zitat mit Tiefgang:

A person’s success in life is determined by having a high minimum, not a high maximum. If you can do something really well but there are other things at which you’re failing, the latter will hold you back. But if almost everything you do is up there, then you’ve got a good life. And so I try to learn how to get through things that others find unpleasant.
