Paul Graham on how to procrastinate well

Paul Graham argues that procrastination can be good if it means putting off small errands to work on more important things, and that the real danger is "type-B" procrastination, where people feel productive while doing the wrong things. He cites Richard Hamming's question of why you are not working on the most important problem in your field, generalized to asking what the best thing you could be working on is. He also notes that big problems are hard to start because they offer no near-term reward and feel frightening, so people often need to approach them obliquely, and he concludes that letting an enjoyable ambitious project pull you forward works better than a to-do list pushing you.
