I feel that as you are plugging away on what many might consider "boring" programming tasks, you become inspired to write your code more cleanly, efficiently, faster as well as automate things and improve your process. If you are focused on one little mundane thing, you have time to really think it over and explore all of the possibilities. I find that creative people will find a way to be creative no matter the task, so nothing is ever really boring.

As you do this with more and more little, boring things, before you know it you will have developed a mastery of your craft.
