Disclaimer: I have like 6 years of experience, I'm not a famous programmer, but I do get people telling me (more than 20 programmers) that I'm a good programmer and I write good code.
Read code, watch people coding, care about your tools, and finally, your code will never be "good enough" you'll always improve.
Read code: Read open source software, from the libraries and frameworks you use for example; That way you'll learn new techniques and ways to organize your code so it's more readable. Also it helps reading books like Code Complete and Beautiful Code. I recommend "Framework Design Guidelines: Conventions, Idioms, and Patterns for Reusable .NET Libraries" even though I'm not a .NET programmer I really like that book.
Watch other people coding: Get together with friends to pair program, or online, most people like to pair program. Or watch some of the new Peepcode videos on experts programming (https://peepcode.com/screencasts).
Care about your tools: Now that a lot of people are using dynamic languages I see it over and over again, people just use whatever editor, debugger, etc etc, care about those things, you'd rarely see myself making a "unused variable" mistake, because I have all the linting tools, and I follow them, same goes to code formatters, etc etc, I recommend VIM to edit code, Git as a communication tool (which is version control), Chrome as debugger. Also try the best way you can to reuse things, framework like Backbone, Batman, Knockout helps a lot with your JavaScript, never use just raw jQuery, it's not needed anymore.
You're never gonna be good enough, there's always gonna be a DHH, Jacob Kaplan Moss, Jeremy Ashkenas (just to name a few) to look up to.
