Everything mentioned (IDEs, typing, automation) is a great advice. But the greatest advice I have been given is "the best code is the one that you don't write". And that's true in my experience. More code means more mess when you have to debug. It also means more time for another developer to get acquainted with your project. So before writing something I often ask myself "do I really need this?" It can be a function, a class, a module or even a graphical asset. It helped me a lot, both on client and personal projects.
