How to become a dramatically better programmer
There's one piece of advice specific to programming which is missing from this listing: Read lots of code in lots of different languages. Aim to read, as a general rule, about twice as much code as you write, and to be able to read twice as many languages as you write in typically.Edit: The average piece of code is written once and read hundreds to thousands of times by people. It's not unreasonable to think of code as a read-oriented activity, not a write-oriented activity.
