How to become good at programming?

[StefanHoutzager]

In my experience a good programmer thinks along with designers / business analists testers etc. Read through designs, discuss your findings, make designs clear for testers en look after testability of your work (which does not mean stuff your codebase with unit tests or use tdd! BDD / TDD criticized).
Futhermore (Turing award winner Leslie Lamport writing):

The second observation is that to write a good program, we need to think above the code level. Programmers spend a lot of time thinking about how to code, and many coding methods have been proposed: test-driven development, agile programming, and so on. But if the only sorting algorithm a programmer knows is bubble sort, no such method will produce code that sorts in O ( n log n ) time. Nor will it turn an overly complex conception of how a program should work into simple, easy to maintain code. We need to understand our programming task at a higher level before we start writing code.
