I don't write code every day, but that is largely due to my military obligations as a reservist. Other than that, I often work on various side-projects and/or help others with their coding woes as a way to learn & help keep sharp. I'm disciplined enough to learn what I need to on my own time whenever I want.

Sometimes I burn out, and in those instances I take my free time away from programming.

The most important take away is to figure out how you want to improve yourself, instill passion in doing so, then executing.
